How to map keys on Linux like my Mac machine

  • 772

On my Macbook, I use CMD+c = SIGINT and ctrl+c = copy (as in copy/paste). On my Ubuntu machine, ctrl+c = SIGINT and ctrl+c = copy depending on the context and that's awful, because it's the same keystroke.

Does anyone know of a good way to map keys on Ubuntu so that ctrl+c = copy and maybe windows key + c = SIGINT?

Furthermore, in the Ubuntu terminal window, to copy/paste I have to use ctrl+shift+c /p which is annoying - I would rather just use ctrl+c / ctrl+p, and to issue a SIGINT, use a different keystroke.

note: the windows key is also known as the superkey: https://en.wikipedia.org/wiki/Windows_key

    You can remap the "Copy" function in the terminal emulator to Ctrl+c in "Preferences" - "Shortcuts". That will override the tty terminal shortcut.

    Options to change the tty terminal shortcuts are more limited. These shortcuts stem from older times, and only Ctrl+letter combinations may be supported. You can change the assignment of these keys with the stty.

    To see all assignments, use the command

    ssty -a

    To change the Ctrl+C assignment which by default is to "intr", use the command

    stty intr "^X"

    Here, intr was remapped to Ctrl+X.

    To automatically remap that key as soon as you start the terminal, add the command to your .bashrc file.
