Yes.  The only problem is getting the visual effect of both icons raising 
up at the same time to indicate that they control related functions.  
Assuming I can get them both raised up, I might have to do something like 
putting a narrow separator between them to finish the effect.

I assume I could do this by tracking mouse entry/exit and manually 
raising/lowering the buttons.  Is there an easier way?
