How can I set a button to move a different object?

Hellooo 
In my game I want to have arrow keys to move my 'main character'. How can I set it so this will work? All I know how to do is when you click or touch the actual 'main character' it moves, but I don't know how to do it so when a separate Actor is clicked it moves the 'main character' (which is a different actor). I tried all I can think of. Thanks I'm kind of new to GameSalad. Thanks for your help

if you spend some time and really focus on those, you'll have a great foundation on how to work with GS.
