Laptop keyboard - numpad commands?
 

I have a laptop and I do not have a numpad section.

Are there commands that replace it?

I need to press + on it somehow and I can't because there is no numpad!

Most laptops have a Fn + F-key sequence to emulate a numpad. There will either be an icon of a numpad or it will say "Num Lk" or something on an F-Key.

On my laptop, I push Fn + F11 and then the U,I,O,K,L,M,7,8,9 keys become the numpad. The keyboard on my laptop already has a + though...between the 0 and backspace.
