Subject: Alex Mole's patch for END and HOME
 http://www.blender.org/pipermail/bf-committers/2003-December/004691.html

Makes HOME and END keys work in text space and text
edit boxes.

I've tested it for some time now and I haven't had any problem or spotted any irregularities of some sort.

One think though. It doesn't update the panning of the text window if the cursor gets out of the screen. I guess someone (more familiar with the code) could look into this.

Really nifty when coding scripts.
