Simple Question

This might sound stupid but i've never needed it before, how would you make it so you enter a region and then press a key it moves you to another region.
ex:
Hey look at me i am pressing "w" and nothing is happening but when i go here and press it, it makes me go there.

I'm making what could be a catchy map

well what kind of a map are you making? if you look around the forum you can find examples of key control

i wanted it secret because if i expose it someone will take it, and if it is a skilled map maker he might be done by end of tomorrow. but i guess that's a little far-fetched. i will private message you.
