The keyboard layout Colemak comes built-in on all Linux distributions I have tried, making it easy for me as a Colemak user to settle in. The only thing I change with regards to the keyboard layout is the position of the Ctrl key, which is placed in the same place as in Qwerty. I am used to have it where the Caps Lock is located, making it more reachable which I find very appealing being a Vim and terminal user.
Colemak made Caps Lock act as an additional Backspace key. I agree that it is more useful than Caps Lock, however, in Vim and in Bash there are so many ways to delete text that leaving the home row is seldom necessary. To set the Caps Lock key to act as Ctrl, we first need to install Gnome Tweak Tool:
$ sudo dnf install gnome-tweak-tool
Next, open Gnome Tweak Tool and select Typing from the sidebar.
Here there are several ways to make Caps Lock to act as Ctrl. However, through my time as a Colemak user, I have discovered that a couple of those options are faulty.
Caps Lock key behavior > Make Caps Lock an additional Ctrl.
This option causes strange behaviors in PyCharm. Try to edit your keymap by adding a keyboard shortcut to any action. When pressing down Caps Lock it appears as Caps Lock; then press down an additional key, for instance A, and it appears as Ctrl + A.
I believe this is the cause of some strange behavior with the Switcher, which is trigged by pressing Ctrl + Tab. When releasing the keys the Switcher is not closed. Instead you have to press Enter to confirm the tab switch, which is really annoying.
Ctrl key position > Swap Ctrl and Caps Lock.
This option causes problems in Gnome Terminal. When pressing Ctrl + Shift, which is required when for instance pasting text with Ctrl + Shift + V, the letter in front of the cursor is deleted. I guess that Colemak's original behavior for the Caps Lock key, i.e. Backspace, takes precedence for a moment.
Ctrl key position > Caps Lock as Ctrl.
This option works fine in both PyCharm and Gnome Terminal.
Please share your own experiences if you are one of the minority with this fringe setup. Sadly I do not (yet) have a comment field on this blog, but I can be reached on Twitter at @DanielJonss.
