ive seen in some games that u can press the "s" key or another besides the up, down, left, right key, how do u do that?

That is a much MUCH more complicated way of doing it, although probably a bit more reliable because it allows you to free up your arrow keys for scrolling and such.

Usually something is constantly selected, like an item shop or a hero standing next to one. The "s" may be a hotkey for an item availiable. So when you press "s" you are actually buying an item or causing some sort of unrelated action that is the condition for the movement trigger. It would be set up maybe like this:

Event:
-(Hero) buys an item

Condition:
-item type of (purchesed item) is equal to (item with "s" hotkey)

Action:

-Remove (last purchesed item) from (hero) inventory
-Whatever action ther use to reface or set movement of a unit for that particular map.
