Hey fellas,
I made a script to help make a .Xmodmap file for Linux, it has fixed many of the frustrations connected to Oracle not bothering to fix all these key map issues I am having on Linux guests - and I'm sure I'm not the only one! I thought I'd share it around, maybe someone can get something good out of it. Find it in my site (http://geek.era.nu/home/vbox-keys).
You can also find a fix for the danish key map there. If you guys and girls out there help out, there could be fixes for a lot more key maps there for other folks to use..
Let me know if it's usable..
