I can't bind keys in ZSH / Where can I get escape sequence for the key in SHELL?

I try to bind Left / Right keys in ZSH, but it seems 1. the escape sequences are wrong or 2. terminal (but all of them? mate xterm, st) is blocking these \E sequences. I can bind for example Ctrl+Left, Shift+Left, Home, End, but I don't know how to bind Shift+Home / End and Left / Right. I've tested following escape sequences: "left" "\eOD" "right" "\eOC" "shome" "\E[1;2~" "send" "\E[4;2~" Is there any command "write \e sequence for the key $key"? Thanks.
