I use CTRL+SHIFT+F in various programs to perform a 'Find in Files' function. (Visual Studio & Atom for example)

  • Other CTRL+SHIFT functions work (+H & +G for instance work fine in those same programs)

  • Tried this same keyboard in another system and CTRL+SHIFT+F works fine (F key works fine in those same programs)

  • Tried removing the device in the device manager for the keyboard and re-discovering

  • Tried resetting the settings configurations for the programs that used this shortcut - nothing

  • Tried this online keyboard tester (http://en.key-test.ru/) and the shortcut works there

  • Windows On-Screen Keyboard also cannot perform CTRL+SHIFT+F in those programs

  • Tried repairing Visual Studio which essentially re-installs it and reinstalling Atom

I'm not sure what else to try. It stopped working when I upgraded from one Visual Studio version to the next available however it also simultaneously stopped working in Atom. Are there some other areas of settings that need to be flushed? I have to assume that was just a coincidence...

  • I had a similar issue today after a Windows 10 patch upgrade. Suddenly, Ctrl+E and Ctrl+F stopped working. It was bizarre. I followed instructions from this answer superuser.com/a/1204019/81913 to run Visual Studio Spy++. Strangely, as soon as enabled logging for all messages, my hot keys immediately stated working correctly again. I never found the root cause.

The culprit was Razer Cortex which had an FPS toggle claiming the hotkey...

Discovered using this method: https://superuser.com/a/1204019/160458

I'm not sure why it worked through Chrome when testing the keyboard online however.

    Wow what a stupid piece of crap Cortex is. Uninstalling it now. I discovered the issue while running X11 server and assumed it was a Linux key bindings issue, and wasted so many hours trying to figure it out.

    This has ruined my VSCode experience until I found this and closed Razer Cortex. What an annoying problem. Thank you!

    This helped me :) Additionally you have to restart the Visual Studio to take the Ctrl + Shift + F to work. Apr 25, 2020 at 14:00

Or you could change the shortcut that Razer Cortex has like:

For the archives: I tripped on this bug with a software of mine today, I was still running Windows 10 1909 (not sure why Windows auto-update hadn't happened yet). I updated my Windows to 20H2 using the Update Assistant, and joyfully note: the bug seems to have been fixed by Microsoft: KeyDown-events for CTRL-ALT-SHIFT-F do occur again.
