Where's the # key in Lion

In Snow Leopard alt-3 used to print a #, in Lion it doesn't. I'v tried different key combination keyboard viewer but still no luck. Any ideas were the # key went?

Since it varies by keyboard layout - why not open your keyboard viewer and find out?

In the US keyboard layout on lion, it's still shift + 3

You have to select this from the menu bar after enabling it in the menu bar

It's still Alt-3 on my UK keyboard -- ###.

I like to use the widget:

CharacterPal

Searching and copying a needed character is faster than with the keyboard viewer:

• You do can look through all characers at once. With the keyboard viewer you need to hold ⌥ and ⇧ to see more characters.
• Characters are sorteded by type: greek, keyboard, math...
• TOP: You can find special (keyboard) symbols like ⌦, ⌘, ⎋, ⏏, ⌤ ...
