2018 is the year of Linux on the desktop—but only for me and only since I started working at a new company where I use Fedora for ~ eight hours daily. Coming from 10+ years of using Macs at work, the biggest change is using Ctrl + C/V for copy/paste and not Cmd + C/V. A couple of weeks in and my hand began to get a slight cramp from using my pinky and index fingers rather than my thumb and index fingers for the operation.

After reading how to remap keys with xmodmap, the configuration below is what I came up with.

Once parsed by Xorg, this lines in this file will remap right alt to right super, left alt to right control and left super to left alt.

$ vi ~/.Xmodmap

clear control
clear mod1
clear mod4
keycode 133 = Alt_L Meta_L
keycode 37 = Control_L
keycode 64 = Control_R
keycode 108 = Super_R
add control = Control_L Control_R
add mod1 = Alt_L Meta_L
add mod4 = Super_R

Confirm that this file is in your home directory, logout, log back in, and test. This may break existing shortcuts, so be sure to remap as neccessary under Settings > Keyboard > Application Shortcuts.
