Suddenly F1 (Context Sensitive Help) inside IDE stopped working
Any idea how can i get my F1 back inside IDE?
Using Windows 10.16299 64, Delphi 10.2 Version 25.0.29899.2631
Don't you have a utility installed aside in Windows that captures the F1 key?
It happened to me someday a long time ago. Once I disabled the utility, the IDE was working fine again.
As a trick, just try to use F1 outside of RadStudio. Does it work in other apps? If yes, then it's related to the IDE; if no, it's because of a 3rd party tool interfering.
I´ve uninstalled Delphi IDE Colorizer and it works again.
I´ll report the issue to the author
You need to download the patched help files from your registered user downloads web page and copy them over your installed help files. The help files are zipped together in RAD Studio 10.2.3 Context Help Patch
The installed help file directory on Win10 is at C:\Program Files (x86)\Embarcadero\Studio\19.0\Help\Doc. There are 7 .chm files (at least for C++ Builder) that need to be copied. Once you copy them, you may need to 'unblock' each from Windows 10 security if they were downloaded from Internet, extracted from the zip file and copied into the installation directory.
To unblock: right-click each chm file and select Properties, then Click 'Unblock'.
After that, context sensitive help should work as usual.
