NO CAPS LOCK!!!

You don't realize how often you accidentally press the caps-lock key until you disable it and have an icon pop up on the screen every time you press it.

Remap Keys in Ubuntu 8.04 (Hardy Heron)

My new Dell Inspiron 1520 keyboard is a little different from my old laptop, and now there's a "menu" key where I'm used to the "delete" key being.

http://www.terminally-incoherent.com/blog/2007/08/02/remapping-the-caps-lock-key/ had a good explanation of how to remap a key, but my case was a little different. Here's what I did:

1. Get the proper key codes

First, I had to find the key-code for my Menu key and my Delete key. At a terminal, type (thanks to Tom for the "| grep keysym" addition to make the output more succint):
> xev | grep keysym

This lets you press keys and get the codes for them. Pressing my Menu and Delete keys, I got a lot of data. Buried in it were the following lines:
keycode 117 (keysym 0xff67, Menu)
keycode 107 (keysym 0xffff, Delete)

Okay, pretty simple. "Menu" and "Delete" are the pertinent bits of data.

2. Make the change

Next, I used VI from a terminal to open ~/.Xmodmap (which didn't exist--I had to create it).
> vi ~/.Xmodmap

(If you don't know VI, I'm sure the regular Text Editor would work just as well.)

In ~/.Xmodmap, I put a single line:
keysym Menu = Delete

Then save the file.

3. Apply the change

Finally, from a terminal, run the following command:
> xmodmap ~/.Xmodmap
