I am an absolute beginner on Ubuntu and Linux. I am currently migrating since Microsoft is supposedly phasing out the support of XP. Running Ubuntu 12.04 I am trying to modify the content of the panel (this is the upper bar as I understand it) so it would show caps lock and numlock status. The info I found on the web more or less said that I needed to super-alt right click on the panel and add the options available from the menu. Hoowever, nothing happens when I super-alt right click. No menu pops up, nothing. I found many posts and websites that gave this key-mouse combo as if it was common use. But for me, it does absolutely nothing. Is there something that has to be enabled to have this possibility?
