After spending hours, I found that xmodmap can be used to remap / key to Left Control key. I used following command:

 $ xmodmap -e "keycode 94 =  Control_L NoSymbol Control_L"

Using xev, I find that keycode 94 is the / key on which I want to remap.

But now this / key (keycode 94) is not working as Control key or even as / key. Any shortcut like Ctrl+C, Ctrl+V or Ctrl+A is not working.

How can I make this key work as Ctrl key properly?

I am using Linux Mint.


Modifiers like Control are somewhat special. The general procedure is something like:

clear control

! ...

keycode 94 = Control_L NoSymbol Control_L

! ...

add control = Control_L
add control = Control_R

You should place these lines in a file, say ~/.xmodmaprc, and call xmodmap ~/.xmodmaprc

  • Thank you for your answer. But I could not understand what does this mean. I am very new to Linux. I tried to put "Clear control" in terminal and it gave an error. Can you please elaborate – Luqman Saleem Aug 13 '18 at 8:12
