For those of you who don't know, the ways the CAPS key on mac works as follows: when you activate the CAPS key, it sends a continuous pulse. On linux (and windows), it only sends one pulse to turn it on and one pulse to turn it off. How can I make my CAPS key work like a mac?
The answer is found in your Ubuntu Desktop Guide.
Click your name on the top bar and select System Settings.
Open Keyboard Layout and select the Layouts tab.
Click the Layouts button, select Options, and find the setting you want to adjust.
While you're in Settings, click Language Support.
You may be prompted to add some language files do this.
Layouts allows you to set up full keyboards of "tweak" your current ones.
