• What is an SSH key?

  - by acidzombie24

  I signed up for github and notice the ssh key option which looked interesting. I originally expected something like an ssl key (name, co name, etc). After going through it i notice i only put a password and it is always myuser@comp-name (this is windows). Why? I thought it was a user/pass id and i can create separate keys for separate purpose for privacy reasons. Now i see i am required to use one to create a repository. Also i see something about a 'private key file' when looking at options. What exactly is an SSH Key and how can i create a separate user without creating a separate login in windows.

• Remapping characters in xmodmap

  - by Jacob R

  I am using a Swedish keyboard, and I want to be able to type braces easier. I planned to map AltGr + å to '}' and AltGr + ä to '{'. However, nothing really changes. I have some other stuff in my .Xmodmap so I know that it gets loaded allright. Here's what I have so far: keycode 35 = slash asciitilde dead_ogonek section dead_ogonek section keycode 49 = asciicircum onehalf keycode 66 = F10 clear Lock keycode 34 = aring Aring braceleft keycode 48 = adiaeresis Adiaeresis braceright where the 2 last lines are the one that should be related to this. What could I be doing wrong?

• What options are there for generating custom text snippets on the Mac?

  - by Moses

  As I am getting more heavily into programming as a job and no longer as a hobby, I am definitely in need of some ways to improve my productivity. One thing that would definitely help in that respect is being able to create customized keyboard shortcuts for text/code snippets. For instance, holding down CMD+L+O+R+E+M will output a paragraph or two of the Lorem ipsum filler text, or CMD+F+U creates a function declaration. What I am ideally looking for is a database where I can store formatted text snippets, bind them to my choice of keystrokes, and then have the text paste whenever I perform the associated keystrokes. Are there any stand-alone applications that can do this for a Mac. Also, are there any text editors / IDEs that have this ability built in?

• Photoshop causing other programs not receive ESC key

  - by user46935

  When I run Photoshop CS4 on Windows 7, other running programs don't receive the ESC key (I noticed in PuTTY and Total Commander's Lister). When I close Photoshop, they start receiving the ESC key again. I tried multiple keyboard layouts, no change. Photoshop is an out-of-box install, no settings changed I exported the list of keybindings from Photoshop (ctrl-alt-shift-k) and ESC isn't used in any combination Why is this? Is there any way to disable or bypass this so that I could use other programs normally?

• "Half" ssh authorization to a server with git repository

  - by hsz

  Hello ! Currently I have purchased web hosting with ssh access. I have created a git repository on it and if I set my public key in ~/.ssh/authorized_keys file, I have access to that repo, I can push/pull data, etc. This solution allows access for every user that has his public key in authorized_keys file. But there is one thing that I want to avoid. Every user can login to the server too and has access to whole ssh account. Is it possible to create a blacklist of users' keys that will not have an access to ssh ? I see it that way: user logs in to a git - ok, allow for every one user logs in to ssh account ~/.profile file is hooked and called a custom script: check user's public key if public key is in ~/.ssh/blacklist_keys call bash exit/logout Is it possible in any way ?

• ubuntu 12.10/linux mint 14 ssh-copy-id doesn't work and returns Ambiguous output redirect

  - by Marc

  I recently got a new computer and I'm trying to use ssh-copy-id to put my keys on another server so I can login without password. but when I try ssh-copy-id -i ~/.ssh/id_rsa.pub user@server and after inputting the correct password it returns Ambiguous output redirect. There are no other messages after that. I thought it was maybe just Ubuntu 12.10 so I installed Linux Mint 14 and sure enough exact same thing happens. I've tried removing authorized_keys from the remote server but that didn't change anything.

• Cmd+Less Than (10.8.2) not working after Xcode (4.5.x) installed

  - by Felix Lieb

  I had to reinstall my MBP recently. I stress Cmd+Less Than a lot for switching between Xcode's main window and the Organizer for documentation. The standard OSX-shortcut for doing that is Cmd + Less Than. After installing Xcode it didn't work any longer. I saw, that Xcode uses Cmd+LT for "Edit Schemes", a rarely used option. Even after deleting the shortcut for "Edit Schemes" in Xcode, Cmd+LT didn't work. How can I get Cmd + Less Than to work again? Mac OS X Mount Lion 10.8.2 Xcode 4.5.2 I have less than 10 reputation on superuser (acutally first post here), so I can't post the answer to my question. Would yo be so kind and upvote this question, so I can officially answer the question? The question, as well as the answer is only correct, if you use German keyboard layout.

• Are Snow Leopard text substitutions scriptable?

  - by yonatron

  I prefer using typographical quotation marks when possible, so I love the Smart Quotes part of Snow Leopard’s text replacement feature. But there are a few cases in which I need to toggle it, and it’s a pain to do so from the contextual menu when I’m typing. Is there any way (preferably via AppleScript, but I can deal with other suggestions) to toggle specific types of text replacement for the frontmost text-input control? And if so, what’s a good way to assign it to a globally-accessible keyboard shortcut (via 3rd-party app if necessary)?

• stdout and key press

  - by Jack

  Hi, when in console, if I press a key, some interrupt controller sends code of that key to CPU, which looks into some table and than represent that keypress by printing some charracter to stdout. But, is keyboard sending an ASCII code of that key, or just some standardised code? Since there is so many languages and extra characters, OS must further translate its code into some character according to user selected scheme, I guess. I ask, becouse I am from Czech Republic, and we use some characters that do not exists in standart ASCII code. So I was thinking, if I enter this character into a console, and then print it, lets say in C++ using cin and cout, and I have set locale to Czech, stdin must actually send some non-ASCII code of the character I pressed to input stream. Am I right?

• Cannot type backquote or backtick in xterm

  - by Cocoro Cara

  Ubuntu 10.10, XTerm(261), Keyboard layout = Canadian Somehow, the backquote (backtick = `) character can't be input does not get entered in XTerm. I type it and nothing happens. The cursor does not move forward. I know it works because I can input it in Terminal (gnome-terminal). The only strange thing is that I have to type the key twice for it to appear. Just to test it, I tried typing it in other applications, and the same thing happens. Have to type it twice in FF, gedit, etc. One more strange thing, I could not input it into this textbox in which I am typing this message. But I can input it in the URL bar, search bar, etc. Someone please help me solve this mystery. I like to use XTerm and I need the backquotes.

• Enter / Return key stops working

  - by andygrunt

  I have a Dell Latitude E5400 laptop running Windows 7. Everything runs fine on it for days then I suddenly notice the enter/return key is no longer working e.g. I could be writing an email, press enter for a new line but it doesn’t ‘register’ – so no new line. I thought it might be some dirt under the key perhaps so I tried running the Windows onscreen keyboard but the Enter key on that doesn’t work either. A reboot always fixes the problem but it’s a pain. Any ideas a) how to fix it and b) out of interest, is there some other key combination that I can use as an alternative to using the Enter key when I need to?

• Why does my PC sometimes think I am constantly pressing the control key?

  - by David Faux

  I was browsing the web with Chrome and pressed f. A search box appeared. I then pressed s, after which Chrome asked if I wanted to save the web page. I soon realized that my PC was thinking that I was constantly pressing the Ctrl key regardless of what program I was using. In response, I tried clicking both of my Ctrl keys a few times to no avail. This problem arises sporadically as I work. I am not sure what is triggering it. Why could this problem be occurring? Is it the keyboard or software? How should I respond?

• Simulating mouse clicks at specific screen coordinates

  - by Matteo Riva

  I would like to be able to bind some keys to mouse clicks done in specific locations. For example: when I press F1 I should get a left mouse click at coordinates 300x350, F2 at 600x350 and so on. Even better if this could be bound to a specific window application so that coordinates could be relative to it instead of the base desktop. Is there a software which allows this? ADDITION: Ok autohotkey is great but I have problems with my particular setup. Quoting my comment below: I'm using it with an old game (championship manager 01/02) which runs in windowed mode (and I have to set win98 compatibility for it to run): I can get the mouse to move but no click goes to the application I have read this FAQ but it didn't help, this is the script I tried: SendMode Play SetKeyDelay, 0, 50, Play F1::Click 42, 191 F2::ControlSend ahk_class main, Click, Championship Manager 01/02 Still no luck: pointer moves but no click goes through.

• Windows won't ctrl+c and ctrl+v

  - by Thomasstuck

  Using Ctrl+C and V I am unable to copy or paste anything. I have tried many different applications and still no luck. I am able to copy/paste via the shortcut menu when you right click the mouse. Ctrl+F works which means the Ctrl button is functional. I've tried restoring to an earlier restore point. I also ran SFC /SCANNOW (System File Checker) which did not find any errors. Ctrl+C and then right click and paste doesn't work either. I have tried with external and internal keyboard and still no luck. I've clicked on all the relevant search results from Google but none of them work for me. Does anyone know what may be causing this issue and how I can correct it? This problem comes and goes at random times.

• de-assign alt + right arrow

  - by jcollum

  I'm trying to map View.NavigateBackward and View.NavigateBackward like so: View.NavigateBackward = Alt + LeftArrow View.NavigateForward = Alt + RightArrow Pretty simple to do in Visual Studio with the Keyboard Options dialog. OK so I've assigned the shortcuts and the NavigateBackward one is working. But NavigateForward, which used to be assigned to Edit.CompleteWord, is staying with its old assignment. I've checked that Edit.CompleteWord is assigned to 'Ctrl+K, W' but the Alt+RightArrow is still behaving as complete word. Is there something special about the arrow keys that I can't assign them? I want to do this so the mouse buttons behave the same in VS 2010 and my web browser. Works fine for the back button, but the forward button won't re-assign properly. Suggestions?

• ^+Left Arrow and ^+Right Arrow suddenly stopped working on OS X

  - by user31122

  Hello. I'm not really sure what to make of this. The key combination of ^? and ^? have stopped working for one of the two users on my OS X installation. I use these keys all the time (switching tabs in terminal, IntelliJ primarily), and it's driving me crazy. On one user account, it works fine. On the other, it doesn't. This happened today and nothing significant comes to mind that would have caused some weird keybinding issue. If anyone has heard of or experienced anything like this, I would very much appreciate your advice! Thanks.

• VIM: How do you get the last ex command you used?

  - by TrevorBoydSmith

  I find that sometimes I write a really long ex mode command that do lots of stuff. They are sort of "mini-scripts" that I write in the text editor then I start ex mode and copy them into the ex line and execute. But then I always end up editing in the ex mode and then I find it difficult to get the changes i did in ex mode back to my text editing session. Using the keyboard, how do you copy the last ex command you used and paste it into your text editor? (Note: This is sort of the opposite of this question "how do I copy/paste in vim ex mode" where the user asks "how do you copy from the text editor and paste INTO the ex mode?". My question is the opposite because I wish to copy from the ex mode and paste into my text editor.)

• Is it possible to use different keyboards for different applications?

  - by Paperflyer

  What I would like is this: I would have two keyboards. One of them is "connected" to Matlab, the other is "connected" to my text editor of choice. This way, I could edit some script and still test some commands in Matlab without having to constantly switch between the applications. Basically, I would want to have an additional keyboard attached to my computer that solely controlled Matlab. That would be awesome! Is there any way to do this? Preferably with OSX, but it would be fun on Windows or Linux, too.

• Startech SVx41HDI Series Server Remote Control Usage Question - How do I switch away from a dead por

  - by tajh

  We have a Startech KVM over IP model SV841HDI and it was stuck pointing a port where the machine has been removed. We ended up having to physically plug something into that port in order to switch ports again, meaning that if someone in support accidentally switches to an empty port, we need to have a documented solution for making it useable again. The unit is old, no longer under warranty, firmware updates for it are no longer available (interestingly it runs a powerPC version of busybox). Since it does work well except for this one catch, we would like to avoid replacing it. Reading the manual, you have a several recommended methods. I tried them. Hit the left CTRL key a few times (as well as all the other popular KVM keys I could think of). The VNC GUI offers lots of buttons - none of them switch away from a dead port. The question is: how do I switch away from a dead port on this particular KVM remotely?

• Launch apps or run commands on Windows via shortcuts

  - by Francisc

  Is it possible to register shortcuts on Windows 7 so that regardless where you are looking (Desktop, a folder etc) the shortcut gets "heard" and the appropriate action is performed. For example, creating a shortcut in the System32 folder which will work if you use Run with the shortcut's name, will not work if you set a key combination when focus is set on the Desktop for example. Is there a native way of registering top-level shortcuts or even an application for enabling this? Example of things I want keyboard shortcuts for: open a specific folder like %path% create a new .js file in the current folder launch an application eventually with its path set to the current location if the app supports this (e.g. command prompt) Thank you.

• Remap key combinations in Windows

  - by nickf

  This question is similar to this one, but the accepted solution doesn't work in my case. I work on two different laptops. On one, the Home and End keys are only available by pressing Fn+Left and Fn+Right. This can make it rather annoying when switching between the two since I always go to press Fn-Right and not get what I want. The tool suggested in the other question is Sharpkeys, however it doesn't recognise Fn+Right as a different key from Right, and I suspect that registry twiddling isn't going to help me here. (?) Is there any way to remap this combination? (I'm on Windows Vista if that helps)

• How do I make my "volume up" more powerful in Win7?

  - by joon

  My volume up button raises the volume by 1%. Its also not a button, it's a weird 'touch' thing which is really really terrible. If I want to lower the volume, I have to awkwardly rub it for a while. If it were to decrease by 5% or 10% it would be a lot better. Can this be set somewhere in Windows/Keyboard settings? I got close to a solution with Autohotkey, where I could do this: a::Send {Volume_Up 5} which would send the volume up command five times, however when I assign it to the volume key, it forms an endless loop since the Send command sends Volume_Up and parses it at the same time. Update: I ended up with this script: $Volume_Up::VolumeUp() $Volume_Down::VolumeDown() VolumeUp( ) { Send {Volume_Up 6} SoundBeep, 750, 50 } VolumeDown( ) { Send {Volume_Down 6} SoundBeep, 750, 50 }

• NextPlease Firefox extension doesn't work in 3.6+. Any updates or similar extension?

  - by Tony_Henrich

  I use a Firefox extension called NextPlease which allows me to use the keyboard to go to the next or previous page on web pages which have Previous/Next paging links. Like the Google search results. I downloaded a version from http://cisengineer.com/firefox/ for my Windows XP. On a Windows 7 FF 3.6 machine, Firefox can't import the extension because it's not compatible with FF 3.6 even though it worked in FF 3.6 in Windows XP. Is there an update to this extension or is there a similar extension? I downgraded to FF 3.5.7 to have the extension working.
