Looking for ALT+LeftArrowKey solution in zsh

Run cat then press keys to see the codes your shortcut send.
(Press Ctrl+C to kill the cat when you're done.)
For me, (ubuntu, konsole, xterm) pressing Alt+← sends ^[[1;3D, so i would put in my .zshrc

bindkey "^[[1;3C" forward-word
bindkey "^[[1;3D" backward-word

(Actually I prefer to use Ctrl + arrow to move word by word, like in a normal textbox under windows or linux gui.)
