More butten event handlers?

when you roll over a button, is there an event handler with an equivelant to hold or something? i want to move a MC’s _x value left or right depending on the button being hovered over (left or right). it only works when the user PRESSES or RELEASES… and the picture in the MC is 4000 pixels wide lol.

any ideas? or will i have to create some sort of while loop?
