I upgraded to 16.2.1 and suddenly I can no longer hit W to cycle between screen modes. Also, Ctrl-Shift-F has been changed from Frame Fitting Options to Fit Content to Frame. I'm leery that lots of other shortcuts have been changed or removed without any notice. Any way to at least get W working again?
Sorry to hear about your experience. I am able to use the W as shortcut between screen modes on my Windows 10 machine and I am also sharing a screenshot for the options I see for Fitting:
I'd suggest you to try resetting the preferences of the app once and see if it helps.
Resetting preferences and restarting the computer did not work. I reinstalled InDesign, though, and it works now.
Did you try:
Edit > Short Cuts > choose set Standard.
I've just checked version 16.2.1 (on a Mac) and W changes screen modes correctly. I suggest you check your keyboard shortcuts
