When activating a keystroke assigned to a button (holding down an ExpressKey or pen button assigned to activate the Option key, for example), the keystroke improperly releases, even when you continue to hold down the ExpressKey or pen button.
What you can do about it while we fix it: Uninstall the 6.3.40-2 driver and then install the 6.3.39-1 driver.
Now my Flip Manually keyboard shortcuts work properly when triggered from the Wacom Cintiq Express Keys .
So the solution for people using Mac OS 10.14 (Mojave) and below is to uninstall the 6.3.40-2 driver and use the 6.3.39-1 driver.
(I am assuming for those using Catalina or Big Sur the current Wacom driver 6.3.42-1 should work properly for executing keyboard shortcuts from the Wacom Express Keys.
Driver 6.3.42-1 is incompatible with Mac OS 10.14 Mojave , but the older 6.3.39-1 works.)

How can I assign the shortcuts keys I have set up for my FLIPS to Wacom Express Keys ?
My method is to mark my KEY drawings in RED , my BREAKDOWN drawings in BLUE, and the INBETWEEN drawings are unmarked. So from a glance at the Timeline I can see where my KEYS, BREAKDOWNS , and INBETWEENS are.
My Flips are controlled with three shortcut keys: F , G , and H
By pressing the F key on the keyboard and moving my stylus over the surface of my tablet I can flip between the KEYS only. (skipping over the frames with Breakdowns and Inbetweens)
By pressing the G key on the keyboard I can flip between both the KEYS and BREAKDOWNS (skipping over the Inbetween frames)
By pressing the H key on the keyboard I can flip between ALL drawings , Keys, B'downs, and Inbs.
Here is the problem: when I assign the shortcut keys ( F , G , and H ) to the Wacom Express Keys , they don't activate the FLIPS mode
when I press and hold on the Wacom Express Key . However, if I press and hold the same keys on the keyboard, it works. I'm puzzled why it does not work
with the Wacom tablet Express Keys. It should be straightforward. If I assign the keyboard shortcut to the Wacom Express Key then that shortcut's function should be activated when I press the Express Key.
Any suggestions on how to make it work ?
