how do you do a hashtag on a 2012 macbook pro?

[Josh Hartley]

i've tried alt & 3, command and 3 I've also tried shift and 3 but still doesn't work so how do you actually do a hashtag?!!!

Assuming you have a standard UK keyboard setting it is alt 3 #####

It's shift 3 on my 2009 US MBP.

See?

If you download symbol caddy (it's free) it will give you access to all the special characters, and when you point to the one you want it tells you the keyboard shortcut for it.

You don't know what hashtag means. From Wikipedia....
"Hashtags are words or phrases prefixed with the symbol #, a form of metadata tag. Also, short messages on microblogging social networking services such as Twitter, Tout, identi.ca, or Google+ may be tagged by including one or more with multiple words concatenated, e.g.:
#Wikipedia is an #encyclopedi
Hashtags provide a means of grouping such messages, since one can search for the hashtag and get the set of messages that contain it."

Methinks you mean hash or pound sign or number sign, eh???????
