I have grown very comfortable to my Colemak keyboard layout (my typing speed has doubled since I started using it). My only problem with it is that there is no caps lock key because under this layout because the caps lock key is a second backspace key. I really miss caps lock so I would like to change the backspace key on the top right corner of my keyboard (not the one right next to the "a") into a caps lock key. Is there a way to do this using xmodmap or some other tool? I am using Xfce.

    +1 for the general interest of the question, but I really can't imagine why someone can miss caps lock... ;-) It's the first thing I ditch on any keyboard (disable it and remap to Compose). – Rmano Jul 28 '15 at 14:35

I figured it out. This link was very helpful: https://butterflyofdream.wordpress.com/2012/09/10/how-to-assign-capslock-on-backspace-key-in-colemak/

Changing the backspace key to a caps lock key is as simple as typing this on the console:

xmodmap -e "keycode 22 = Caps_Lock"

    This seems to work, but I think the most important command now would be how to reset this back to Backspace: xmodmap -e "keycode 22 = BackSpace" – rubo77 Oct 12 '15 at 10:25

Edit /usr/share/X11/xkb/symbols/de (where /de is your language) and add this section in the first block, that you use in your language:

        # replace Caps with Backspace
        key <CAPS> { [ BackSpace            ] };

But I would recommend better to replace it with AltGr and them map AltGr+f to backspace:

        # replace Caps with AltGr
        key <CAPS> { [ ISO_Level3_Shift            ] };
        # Add Backspace to AltGr+f
        key <AC04> { [ f, F, BackSpace, BackSpace  ] };

So you can add more useful shortcuts like here: Configure Caps Lock as AltGr and Arrows like in vim
