My life without CAPSLOCK
Yesterday I spotted the option "Make CapsLock an additional Ctrl" in the Gnome keyboard preferences (Desktop > Preferences > Keyboard > Layout Options > Ctrl key position). I enabled it, obtaining the end of errors due to erroneous enabling of Caps Lock (as suggested to me by several people at DebConf6, but so far I've been too lazy to learn how to do it with xmodmap).
In addition to feeling more relaxed when using Vim (we all know how dangerous can be Caps Lock in Vim!), using Caps Lock as CTRL is actually really handy, since key combinations involving CTRL can be formed moving the left pinky way less: probably a dream of all Emacs users out there
Now it is just a matter of training my left pinky to stop going in the bottom left corner of the keyboard ...
