Character moving steadily

In my game, I am using sprites as buttons so that I can put the sprites on top of my canvas. I am using the sprites to move a character to the right and to the left, and it works fine by just pressing the sprite, but I wanted to know if there was a way to have the character keep moving forward if I held the sprite.

 Thanks for any help!

in the sprite touchdown event set the speed of the character to a value > 0

in the sprite touchup event set the speed of the character to 0

Thanks! This answers my question pretty well.
