Like the title says, on both my desktop and laptop, both with the Windows 10 May 2019 Update, the hotkey for “Select Linked Flat Faces” doesn’t work at all. Shift+Ctrl+Alt+F doesn’t work anywhere.
Just to check with anyone else with the May 2019 Update of Windows 10, are you experiencing the same?
The hotkey combination works fine on my older Windows 7 laptop…
I do encotered same bug, it is broken in all programs.
I noticed this as well. It’s really weird.
every other key works with ctrl+alt+shift
not many programs do have that crazy key combinations: https://defkey.com/what-means/ctrl-alt-shift-f
it is no big deal to change that one shortcut to something else, but that’s interesting why is that particular one not working
BTW does you right alt works in blender shorcuts? Mine acts like it was ctrl+alt simultaneously clicked.
Well, In Blender 2.80, I now made a shortcut for select linked flat faces. Being Ctrl+Alt+Windows-key+F, and also in 2.79 (which I still use for certain import-export support) 
But no, My Alt seems to work just fine. Weird…
