Toglle between code and design mode

I used TMS WebCode VSC in the past and today gave it another try. Correct ne when I am wrong but I remember that with Ctrl+F12 one could toggle between code and design. This doesn't seem to work (any more?). The manual (TMSWEBCoreVSCSetupGuide.pdf) says

. Seems like an odd combination.

F12 is already used in Visual Studio Code, so we chose Ctrl-F12
Unless some other extension trapped it already, Ctrl-F12 should still work. It is still working here at least.

Unfortunately Ctrl-F12 doesn't work on my computer. I get the Search files by name list.
I am using the latest VSC.

What other extensions do you have installed?

I solved the issue by removing the shortcut via File, Preferences, Keyboard Shortcuts.

Delphi shortcuts were installed!
