I have two operations that I do all the time in Emacs:

1. Create a new buffer and paste the clipboard. [C-S-n]
2. Close the current buffer. [C-S-w]
3. Switch to the last viewed buffer [C-TAB]

I feel like a keyboard acrobat when doing the first two operations. I think it would be worth trying some custom keybindings and macros.

A few questions about this customization:

1. How would I make a macro for #1?
2. Are these good keybindings (i know this is a bit subjective, but they might be used by something popular that I don't use)
3. Has anyone found a Ctrl-Tab macro that will act like Alt-Tab in Linux/Windows? Specifically, I want it have a stack of buffers according to the last viewed timestamp (most recent on top). I want to continue cycling through the stack until I let go of the ctrl key. When the ctrl key is released, I want the current buffer to get an updated position on the stack.
