The next Logger32 update will include support for the Griffin PowerMate USB knob.  I you have a Griffin (or maybe a pryde of Griffins :) set them up as follows:

To control the primary radio, program your Griffin:  CTL+> for up xHz, CTL+< for down xHx, ALT+CTL+> for up 1000Hz and ALT+CRL+< for down 1000Hz.

To control the SO2R or SO2V, program your Griffin: CTL+upArrow for up xHz, CTL+dnArrow for down xHz, ALT+CTL+upArrow for up 1000Hz and ALT+CRL+dnArrow for down 1000Hz.

To enable the global hotkeys for the Griffins, click SETUP | HOTKEYS | POWERMATE GRIFFIN USB VFO KNOB.

The above description of Griffin programming refers to xHz.  xHz is a small frequency increment.

Logger32 has a feature that allows the user to roll their mousewheel over the frequency display on the Logbook Entry Window.  This moves your VFO up/down by small increments.  Right click on the frequency on the Logbook Entry Window to show a menu of frequency increment options.  Set this to suit your operating style.  If you are familiar with rolling the mousewheel over the frequency display to move the VFO up/down, then you know that holding down the SHIFT key while doing this multiplies the increment by a factor of 10.  The same applies to spinning the Griffin wheel.

For the more creative user, you could of course program a single Griffin to control both radios: CTL+> for primary radio up xHz, CTL+< for primary radio down xHz, CTL+upArrow for SO2R/SO2V up xHz, CTL+dnArrow for SO2R/SO2V down xHz,

What did I say?  Correction on PowerMate Griffin programming ... To control the primary radio, program your Griffin:  CTL+rightArrow for up xHz, CTL+downArrow for down xHx, ALT+CTL+rightArrow for up 1000Hz and ALT+CRL+leftArrow for down 1000Hz.  For a single Griffin controlling two radios, try something like this: CTL+rightArrow for primary radio up xHz, CTL+leftArrow for primary radio down xHz, CTL+upArrow for SO2R/SO2V up xHz, CTL+dnArrow for SO2R/SO2V down xHz,  Even if you don't have a Griffin, you can simulate the commands by first enabling the HotKeys, then typing the commands at the keyboard.  Nothing better than a VFO knob next to the keyboard.  It's been a long day.  73.
