zsh key binding: cannot bind to an empty key sequence

Question

The most recent update to zsh produced the following error on Mac OS X Maverick: /Users/[username]/.oh-my-zsh/lib/key-bindings.zsh:bindkey:23: cannot bind to an empty key sequence

The corresponding lines are:

bindkey "${terminfo[kpp]}" up-line-or-history       # [PageUp] - Up a line of history
bindkey "${terminfo[knp]}" down-line-or-history     # [PageDown] - Down a line of history

There is no PageUp, PageDown, Home and End on the Mac keyboard. I wonder why the correct key code is considered nil by bindkey or how the conditional should look like if ${terminfo[kpp]} is nil. Any ideas?

Answer 1

It has to do with $terminfo not being consistent across platforms, the commit has been reverted see https://github.com/robbyrussell/oh-my-zsh/issues/2608 for details. If you got the hub tool installed the quick fix is:

cd ~/.oh-my-zsh 
hub checkout https://github.com/robbyrussell/oh-my-zsh/pull/2625 terminfo_fix

and reload your shell. Without hub you need to setup the remote for the PR first and pull from there.
