Defult keys for setting prop RPM are + and - on the keypad.

yes red.

take a peek at the e6b calculator.  your throttle alters manifold pressure and + & - keys on keypad adjusts rpms.

IIRC the - and + on keypad technically are a propeller governor and not a true pitch adjuster.
Course still working on first cup of coffee. We so low on instant it's 50% hitest and 50% decaff too.

You can't directly control prop pitch.  

When you change the throttle setting, there is a governor that adjusts pitch to maintain the set RPM.  

When you change the RPM setting with +&- you are changing the RPM the governor will automatically maintain via pitch adjustments.

There's nothing to be gained in terms of performance by reducing RPM. It's purpose is to maximize range via minimizing fuel consumption. You reduce RPM and MAP. Check E6B for the cruise settings. If you happen to have a Specific Engine chart for your particular aircraft, you will find settings to maximize range and/or endurance that will require lower RPM and MAP settings than shown on E6B. And yes, Aces High does conform to the charts for all American fighters.
