To setup the various buttons on the client, you'll want to know the following:
To set up Your attack targets, under Combat, listed as Attack 1, Attack 2, etc. you will want to manually type once connected and logged into the MUD:
hit1 [your first hit target]. Eg. hit1 stormtrooper. Then whenever you press the Attack 1 button the mud will perform the hit command on the first thing with the stormtrooper keyword in your room.
The same logic goes with Ability [n] and Alias [n], the difference being that you store the entire command in the respective button. Here's some examples:
hit1 wookiee = pressing Attack 1 button executes hit wookiee
hit2 commando = pressing Attack 2 button executes hit commando
alias2 hyperspace coruscant = pressing Alias 2 button executes hyperspace coruscant
abil3 useforce 'force stun' = pressing Ability 3 button executes useforce 'force stun'
Note that these settings are saved on the character, on the MUD, not on the mobile client.
Any questions please ask on the chat channel in-game.
