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
