Jared already told me so ;-)
Since I am not the only one who misinterpreted the menu help, how about a 
little more verbose descriptions:
Size of via tool +5 mil              Shift+V
Size of via tool -5 mil         Shift+Ctrl+V
Drill of via tool +5 mil               Alt+V
Drill of via tool -5 mil         Shift+Alt+V

Same misunderstanding for me with key "T" for text size.
I would suggest: 
Size for new vias +5 mil              Shift+V
But I always use 
"Route Style" dialog in PCB for via size -- never needed size adjustment
on the fly.
