keyboard shortcut for zoom - make it work like Photoshop?

Hi - sorry if this is an easy answer I should have found on my own.

I want "zoom" to work like it does in Photoshop - "ctrl +" for zoom in, "ctrl -" for zoom out - right now those key combinations change track height, which I rarely need to change, instead of zooming, which I do all the time.

I found one other person had asked this question and no one had answered it.

Is there a solution? Help!

thanks,

dave
