Bind keys in macos to move forward/backward a word at a time

I noticed that when using Kitty + Zsh in macos jumping forwards and backwards one word with the usual key combination (option + arrow) was not possible.

The following bindkeys can be defined in Zsh to achieve that behavior:

bindkey "\e[1;3D" backward-word # ⌥←
bindkey "\e[1;3C" forward-word # ⌥→
