Unless you like to yell at people all day1, you probably don’t use your caps lock key much. But since none of us are perfect, you do probably use your delete key2 a lot. So, why not save your right pinky some strain, and replace your caps lock with a second delete key?
Here’s how you can do it on a Mac running Yosemite.
Step 1: Disable your caps lock key
Go into your System Preferences, select the Keyboard pane, and then click the button labeled Modifier Keys. There you can set your caps lock to No Action. You’ll likely want to do this for all your keyboards in the Select Keyboard dropdown.
Step 2: Download and install Seil
Step 3: Configure Seil
Once you have Seil installed, go ahead and open it. The first option lets you reconfigure the caps lock key. Check the box to activate the caps lock key change, and set the keycode to 51. Once you’ve entered the keycode, it should be ready. You can quit the Seil app now4.
Taking it further
Even if you decide not to learn [Colemak], I recommend remapping the Caps Lock key to Backspace. That change alone results in a 15%-20% reduction of finger distance on QWERTY. After experiencing the difference perhaps you’ll be more motivated to learn an alternative layout.
I haven’t taken the plunge and switched to Colemak. However, as someone with more than a passing interest in preventing RSI, I can see the attraction. Colemak, and the better known Dvorak layout should reduce typing strain by making your keyboard use more efficient than QWERTY5.
Delete is the Mac equivalent of backspace. ↩
