Quick Linux Tip: Remap “Back” Key to Win Key

January 22, 2010

Thinkpad keyboards are the best laptop keyboards I’ve seen. The function keys are placed in groups of four, with gaps, like on a full-size keyboard. The arrow keys are located lower than the rest of the keys, for easy tactile identification. And best of all, the Insert, Delete, Home, End, and Page Up/Down keys are grouped in the familiar 2×3 box pattern one would expect to see on a desktop keyboard.

The only thing I’m missing is a right Windows key (technically a Super key). A lot of handy Amarok shortcuts use the Win key, such as Win+O for displaying the OSD, or Win+P for firing up the playlist. I’ve also set Win+Plus and Win+Minus to change the volume. With only a left Win key, all of the above-mentioned shortcuts require two hands. So what can I do?

I can remap the “back” key (XF86Back) located above the left arrow key to act as a right Win key. (The back key itself is not that useful — in most sensible applications, one can use Backspace for that purpose.)

First, I open up xev and press the key to find its keycode: 166. Then I use xmodmap to test the changes live:

xmodmap -e “keycode 166 = Super_R”

Finally, I save the setting in my ~/.Xmodmap:

keycode 166 = Super_R

Mission accomplished.

Why Open Source Rocks (and the music industry does not)

If you ever looked for song lyrics online, you know how most lyrics sites are. Plenty of ads, popups, silly scrolling flash gadgets, bad punctuation, and no easy way to send in corrections. Why not apply to lyrics the same community-driven editing model that has made Wikipedia so successful?

LyricWiki.org has done exactly that, and more. They have provided an API, making it easy for media players to query the database and fetch the lyrics for a specific song. To get an idea of this project’s success, check out these stats. At the time of this writing, LyricWiki is the fifth largest MediaWiki in existence, and the largest wiki that is not a Wikipedia or Wiktionary. What an inspiring example of a community built around the ideals of improving content and making information available. What could go wrong?
