For example in my .Xresources I have a line URxvt.keysym.Control-Left: \033[1;5C. I don't know very well what \033[1;5C means, but by having bindkey "^[[1;5C" forward-word in my .zshrc it allows me to walk left a word in terminal which is useful.
Because I use vim, I wanted to map ctrl+w to delete a "word" and ctrl+shift+w to delete a "WORD". If I add URxvt.keysym.C-W: something in .Xresources , pressing ctrl+shift+w will write something. What can I put in that something? I'm thinking maybe I should put some symbols like \033[1;5C so I can refer to them in .zshrc, but I don't know what those symbols mean and don't want to bind some wrong key combination and press it by accident.
So what does something of the form \033[1;5C mean and where can I read about it? And what can I put so it doesn't conflict?
