Tweaking Keyboard from the Command Line

I love swapping my CAPS and CTRL keys, and I never found the tweak tool solution to be very elegant. I found this quick solution, which didn't require me to install anything. I've included it below for reference. Great fix!

Open the following for editing:
sudo nano /etc/default/keyboard

And edit
XKBOPTIONS="ctrl:swapcaps"

Then, reconfigure:
sudo dpkg-reconfigure keyboard-configuration

And just go through the prompts as they are.
