Writing your own OS to run on a handmade CPU is a pretty ambitious project, but I've managed to get it working pretty well so I'm going to write some notes about how I did it.

| ; Colemak layout for AutoHotkey (MS Windows) | |
| ; 2006-01-01 Shai Coleman, http://colemak.com/ . Public domain. | |
| ; See http://www.autohotkey.com/ for more information | |
| ; For this to work you have to make sure that the US (QWERTY) layout is installed, | |
| ; that is set as the default layout, and that it is set as the current layout. | |
| ; Otherwise some of the key mappings will be wrong. | |
| ; | |
| ; This is mainly useful for those who don't have privileges to install a new layout | |
| ; This doesn't support the international features of the Colemak layout. | |

| ; Use just the Home key for Win Tab | |

| ; Use the End key to quit programs | |
