This document was written for a late 2012 Retina 27" iMac that I moved to linux due to a hardware instability with Mac OS.

Install Tweak Tool (This is the name of the app in your app list.)

sudo apt install gnome-tweak-tool

Launch Tweak Tool

1. First swap the dashboard hotkey to the right side and then under "Additional Layout Options" you can use "Ctrl position/ Swap Left Win with Left Ctrl" to good effect.

2. You can use "Ctrl position/ Swap Left Win with Left Ctrl" to good effect.

For Ubuntu Bungie I had to remap the super key.

Binding Super to Ctrl What about binding your left Windows/Logo/Super key to act as another Ctrl key?

You can achieve that with the following xmodmap commands:

remove mod4 = Super_L
keysym Super_L = Control_L
add Control = Control_L

Assuming you saved the above lines as super_as_ctrl.xmodmap you can test out the effect by executing

xmodmap super_as_ctrl.xmodmap

To make the change permanent (surviving re-login/reboot) rename the file to .Xmodmap in your home folder.
