When I ordered my MacBook Air the only options I had for keyboard were UK English, and French. No US English when ordering from the UK store you see. So, I was trying to hack around with rcov today, and needed to alter some source. I wanted to copy and edit a line of code, preserving the original. To do this, I was just going to hash out the line, and put my altered line below. That's where I encountered my issue.
THE UK KEYBOARD LAYOUT HAS NO # SYMBOL PRINTED ON IT!!!!
Luckily I found this page - Hat tip to QuiteTall.
ALT-3 for people who can't be bothered clicking thru.
I mean come on - the keyboard has symbols such as § and ±, but no #?!?!?!? What's going on with that?
