The character with code 0x1B (generated by Ctrl+[) is not meant to be used directly by applications, because it was designed to serve as the signal which starts a control sequence. I never input control sequences by hand (does anybody do?), thus I do not need any keybinding to produce the escape code itself. So, I would prefer to use these buttons for something else. You see, these two buttons (Ctrl and [) occupy a convenient place on the keyboard and are thus convenient to type, and it's a pity that this keybinding is just wasted.How do I make Ctrl+[ generate the control sequence of my choice? (both under X and under Wayland)
How to make C-[ generate a given control sequence?
