Hi there, I recently tried updating my copy of Okular, and found that the menu accelerator behaviour changed. Originally I could press Alt, then press F, to open the file menu; but in the latter version I have to hold Alt and press F.
I couldn't find anything is Plasma's system settings related to this, so after some helpful tips from tosky in #okular I bisected the change in Okular's behaviour to the following Nixpkgs revision: https://github.com/NixOS/nixpkgs/commit/c172f144f405 kdeApplications: Use latest qt515 by default This commit updates the version of Qt used to build the KDE Frameworks and Applications from 5.14.x to 5.15.0 . However, that commit doesn't affect Kate; I bisected again to find https://github.com/NixOS/nixpkgs/commit/0263f626a060 qt-5: 5.15.0 -> 5.15.2 Which causes the same behaviour change for Kate. Initially I was confused as to why a Qt version update should affect this, as I assumed the functionality was provided by KDE Frameworks, but it looks like Qt provides a menu accelerator class, so perhaps that's at the bottom of the stack here. It's worth noting that in the versions of Okular/Kate with the press behaviour, the accelerator underlines are permanently visible, which is probably related. For what it's worth, my copy of Firefox doesn't require a hold, but my copy of Libreoffice does, so I guess there isn't much of a standard. Anyway - I can't tell whether this is an intended change, so I'd love to hear from someone who knows. Kind Regards, Craig Hall
