Creating a .Xmodmap file for Linux is very easy. This file contains all of the keyboard mappings for the keyboard keys for your system.
jason@darknet:~$ xmodmap -pke > ~/.Xmodmap |
Now use less to view the completed file.
jason@darknet:~$ cat .Xmodmap |
This file can be edited if you wish to disable the annoying Caps lock key. This is very useful if you find that key annoying as I do. This page has the solution to performing this task.
