Moving Storyline Graphics / Screen Elements Incrementally w/ Keystrokes

Hi all,

Has anyone found a way to move on-screen elements (graphics, backgrounds etc.) incrementally or in smaller movements than the default?

Typically in programs like Photoshop for example, you can hold SHIFT and move the on-screen graphical elements in much smaller increments to be certain of desired placement. 

Currently in Storyline, I have to right-click the object or group of objects and use the Size/Position menu and adjust Horizontal or Vertical Position -- then check again (without the highlight alignment on), and then repeat this laborious process which costs lots of time.

Is there a key to hold down while moving items w/ the arrows to decrease the amount that graphics move?

I'd be most grateful for any hints or tips in this direction! 

Thanks!
