Strange question I know, but as I found out from here, the hash key, #, is ALT + 3 on a UK Mac keyboard instead of near the Enter key on a normal UK PC keyboard.

  1. Whilst alt+3 provides a hash key in nearly all my apps, it doesn’t in the terminal.

    Any ideas on how to get a # in Terminal’s command line and in vim?



  2. Rob, I just tried ALT + 3 in both iTerm and Terminal and I get a hash symbol. I did load up VIM but I haven’t foggiest on how to use it so can’t confirm if # works for me there.

  3. @Rob:
    Hi there, I know I’m a bit late but…
    The reason hash isn’t working in terminal is probably because you’ve got ‘option sends meta’ enabled in the terminal options. I also have this problem, but I have no idea how to send a hash from the keyboard when this is enabled :-/
