Other GNU/Linux tips
When using GNU Emacs, the Ctrl key is used much more than Alt. Therefore it is a good idea to swap these keys. To do this in Gnome:
- System=>Preferences=>Keyboard=>Layouts=>Layout Options
- In Alt/Win key behavior select Control is mapped to Win keys (and the usual Ctrl keys);
- In *Key to choose 3rd level** select Right Alt key never chooses 3rd level;
This will swap Ctrl and Alt.
