[1] https://neo-layout.org [2] https://en.wikipedia.org/wiki/Keyboard_layout#/media/File:ISO_keyboard_(105)_QWERTY_UK.svg STEPS TO REPRODUCE 1. Switch the keyboard layout to German (Neo2) 2. Open a „Save file“ dialogue 3. Press the "#" key OBSERVED RESULT Quick filter bar opens EXPECTED RESULT No action (key is used as a modifier like shift) SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.19.0 Qt Version: 6.10.0 ADDITIONAL INFORMATION The use of the left-hand mod3 key (caps lock) does not open the quick filter. The key used for "#" in the German layout is apparently used for "\" on the US layout. It is or was used as a short cut for opening the filter bar — on the US layout that is. I could not open the filter bar using any single key with the “normal” German "qwertz" layout, especially not # (\ on the US layout) nor with Alt Gr+ß (prints \ on German layout). So it does not appear to be really hard coded. I’m reasonably certain I found the code which represents the filter bar (KFileWidgetPrivate::initQuickFilterWidget()) and where it’s instantiated but understanding how a key triggers showing/hiding it is where I’m currently stuck. First version I got around to analyse this with was kio 6.17.0-1 on Arch Linux. https://github.com/KDE/kio/blob/508f830e56ca89086a3b79ee2713138751321d6c/src/filewidgets/kfilewidget.cpp#L1362 https://github.com/KDE/kio/blob/508f830e56ca89086a3b79ee2713138751321d6c/src/filewidgets/kfilewidget.cpp#L404 Bonus Bug: When trying to add a new keyboard layout in the system settings I can filter using umlauts, e.g. "ö", but the filter on the variant (right) side of the dialogue will be empty. If I use "deu" instead I can select "Deutsch (Österreich)" on both sides. So filtering using umlauts is probably broken.
