How do I remap the arrow keys using AutoHotkey?

In this question about rebinding the controls for The Binding of Isaac someone suggested using AutoHotkey, and gave an example of moving wsad to edsf. My question is how do I move the arrow keys? Two of my arrows are broken, so I want to switch them to the keyboard. What are the symbols for arrows in the hotkey file?


The arrow keys are just called "Up" "Down" "Left" and "Right" in AHK. A sample script to remap your arrow keys to i/j/k/l as up/left/down/right:

i::Up
j::Left
k::Down
l::Right
