Remapping a keyboard
One month ago I've accidentally damaged my Macbook Pro keyboard so it completely stopped working. I've decided to replace it with a new one by myself, so I ordered the new keyboard from Ebay. While I was waiting for the parcel to arrive, I used an old-school Apple wireless keyboard, like this one:
What a torture it was! It weighs as much as kilo, so my notebook with mouse, keyboard and supply unit had more than 4 kilograms in weight. It was terribly heavy to carry.
Finally, the new keyboard module for my macbook arrived. I successfully replaced it, thanks to iFixit guide. But then I faced another problem: “ ] ” button worked as Caps Lock. Even Caps Lock button LED state was changing. A Many Tricks’ Key Codes app helped me to find out that it sends exactly same events to system as Caps Lock.
I decided that I can live without Caps Lock but cannot live without ] button as Objective-C syntax uses square brackets widely. So I planned to remap both Caps Lock and ] keys from Caps Lock functionality to ].
The solution was:
- Go to Keyboard → Keyboard Pane in System Preferences and remap Caps Lock to “No Action” (see screenshot),
- Download PCKeyboardHack and KeyRemap4MacBook apps,
- Install both of them,
- Search through both apps and find a suitable option (for me, it was an option Change Caps Lock in PCKeyboardHack),
- Change keycode of the key that you want to remap.
You'll also have to know the keycode of the key that you want to turn to. I spent a fair amount of time to find the keycodes table (as it is NOT connected with ASCII codes which are easy to find). I finally found it here: Virtual key-codes. Mirror link to pdf: here.
Hope this guide will save time for others.
