[RWP] How to Maximize While in Reaper?

[Indigo]

This may seem too simple, but how do you maximize while in Reaper, in 
your particular screenreader?
Running Window-Eyes, NVDA also; When I'm in Windows, outside  of Reaper, 
I press alt+spacebar; then arrow up twice to maximize; which is waiting 
there for me.
Maybe there's another way while in Reaper?
I can't press Alt+spacebar in Reaper, because the spacebar just starts 
play, and alt+spacebar seems to mean nothing to ReaAcces; so I'm left 
with no way I know to maximize.
Thanks for any tips,
Indi
