[Nottingham] Vim on OS X

[Joshua Lock]

Hi list,

Religious flaewars on OSs and editors aside I'm spending more time in
Vim, but one thing is keeping me back when I'm running in OS X's
Terminal.app on my Apple laptop - I can't work out how to insert a #
character.

In Cocoa apps its <alt>-3 but when I'm in insert mode in Vim this
doesn't seem to work.

I'm sure loads of people have had this problem but I can't find a
search term that is unambiguous enough to find the results on Google.

Any ideas?

Best,

- J
