Take a look at the Blizzard map sheep tag or whatever its called. It has optional movement controls. You should be able to figure out how to do it based on that. If that dont help try to find a map with optional controls take a look at it. If its locked try to contact the creator and maybe they will send you the trigger.

Use items. Make custom items with those letters as hotkeys. Then force the player to select a shop that sells those items and has a hero of that player's next to it. Then make triggers so if a player buys an item it makes him go forward, turn, etc...
And make sure the items are free and restock every like 10th of a second.

if you don't want to use item shop controls, you can make custom abilities with hotkeys fitting what you need, as well as just using stop for s, and have the spells be summonns to make it easier to tell when the spell is cast, but the summon must be killed instantly and cooldown is needed to be really small/none.

so far i have the track done the jumps, selectors(no cars yet:( ), and the nass. heres the map if you want to check it out so far

question. could i just convert a trigger to java and do keystrokes from there?
