126: What if I don't have an Escape key? Type `C-[' instead. This should send ASCII code 27 just like an Escape key would. `C-3' may also work on some terminal (but not under X). For many terminals (notably DEC terminals) `F11' generates ESC. If not, the following form can be used to bind it: (define-key function-key-map [f11] [?\e]) ; F11 is the documented ESC ; replacement on DEC terminals.
