On Windows, if you hover over a menu entry (f.i. Tools - Spelling) and then press F1 while the mouse is over the entry, the corresponding help page will open. This also works with "gen" on Linux... I can't tell about MacOS. However it does not with with gtk3 or kf5. I believe it should work in all backends. Is this fixable in gtk3 and kf5?

For kf5 VCL, it is only usable since 6.4, and F1 on menu items never worked.
(In reply to Rafael Lima from comment #0) > I believe it should work in all backends. Is this fixable in gtk3 and kf5? gtk3 and kf5 are using native Gtk/Qt menus, so making this work might require hooking into their key event handling, but should probably be doable.

I had quickly experimented with this a bit, can try to find some time this weekend to either turn it into an actual patch or something that at least gives some input on how to hook into the event handling. (Code for the kf5 menu is in vcl/qt5/QtMenu.cxx .)

Michael Weghorn committed a patch related to this issue. It has been pushed to "master": https://git.libreoffice.org/core/commit/2ef9880f97de6629ddef12eb788123ab4be1ec83 tdf#156376 qt: Open help for focused native menu entry on F1 It will be available in 24.2.0. The patch should be included in the daily builds available at https://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More information about daily builds can be found at: https://wiki.documentfoundation.org/Testing_Daily_Builds Affected users are encouraged to test the fix and report feedback.

(In reply to Rafael Lima from comment #8) > Do you plan to fix this in gtk3 as well? If not, we could CC someone else. No, I don't have any such plans at the moment, and my gtk experience is also much more limited.
Caolán, any insights on using F1 on menus with gtk3? Same with: Version: 6.0.0.0.alpha1+ Build ID: 6eeac3539ea4cac32d126c5e24141f262eb5a4d9 CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3; Locale: en-AU (en_AU.UTF-8); Calc: group threaded
I can't comment on the kf5 menus, but there are two types of menus in gtk, the various arbitrary menus like context menus and then the other types of menus which belong to the toplevel menubar. For the toplevel menubar we provide an fairly abstract menumodel to gtk. https://docs.gtk.org/gio/class.MenuModel.html and https://developer-old.gnome.org/gio/stable/GMenuModel.html As far as I know there is no field/support in that MenuModel which supports the concept of help for a menu entry and no straightforward way to access the underlying widgets that implement the menu in order to hook into some F1/help activation (the menubar and menus might not even be in the application, the Unity thing of a macOS-like shared desktop menubar might have fallen out of favor but the apis we use are theoretically supportive of that so the menumodel might not even get consumed by a traditional menubar+menu. I could see that hacking the arbitrary menus might be doable to get help in there, but I never could see how to do it for the toplevel menubar+menus.
