Shell

My laptop keyboard faced a particular problem with both Ctrl keys not working. It was a hardware issue and only keyboard replacement would resolve. I searched for alternatives where I could replace any key not being used to Ctrl key. xmodmap is a utility for modifying keymaps and pointer button mappings in Xorg. To do the same, I replaced the Menu Key in keyboard(keycode = 135) which acts like a right click and mapped it as right control key. To do so, one would need to create the file ~/.Xmodmap and update with the following data. !clear the control keys
clear control
