:unmap <Alt-3> Esc
:unmap <press Alt-3>

Solution

  • The problem was in your iTerm configuration, which was set to send ESC+3 when <Alt-3> was pressed.

    You can solve the problem be going to iTerm2 menu Preferences > Profiles > Keys and setting Left Option (alt) Key there, changing from "Esc+" to "Normal".
