NAME<P>
xmodmap - utility for modifying keymaps and pointer button mappings in X
<P>
SYNOPSIS<P>
xmodmap [-options ...] [filename]
<P>
DESCRIPTION<P>
The xmodmap program is used to edit and display the key-board modifier map and keymap table that are used by client applications to convert event keycodes into keysyms. It is usually run from the user's session startup script to configure the keyboard according to personal tastes.

For more info do a man on xmodmap. I routinely use it on all my remote login sessions to disable the "Caps Lock" key, which is real annoying using VI on a small notebook keyboard
