I don't believe I've ever had a keyboard with Home/End keys. What do they do on OS X/Linux?

[dTal]

Home and End move the cursor to the beginning and the end of the line, respectively, on any computer except a Mac.

It's extremely unlikely that you've never had a keyboard with these keys!

[copperx]

Control a and e (the Emacs shortcuts everybody knows) work on all Mac applications. That’s why home and end work differently.

Vim user: I think you mean ^ and $

[SecurityLagoon]

You have almost certainly had a keyboard with these, even if it was behind a fn key combo on a laptop.
