SUMMARY The "extend selection" shortcuts in Qt text input controls (except for certain applications which implement it themselves such as Kate) are always mapped to ctrl+shift+left and ctrl+shift+right (and shift+pos1/shift+end and so on). This works fine as long as you keep the default bindings for text movement (ctrl+left/right, pos1/end, ...). However, if you rebind them to e.g. alt+left/right and meta+left/right, the extend selection shortcuts no longer match up and as far as I can tell there is no way to rebind these separately. STEPS TO REPRODUCE 1. Bind "Backward Word" and "Forward Word" to alt+left and alt+right (in Shortcuts -> Navigation) 2. Select a normal Qt input field 3. Try alt+shift+left to extend selection backwards a word OBSERVED RESULT Nothing happens, as ctrl+shift+left is still the shortcut for that action EXPECTED RESULT alt+shift+left selects backwards a word, or there is a separate shortcut you can set for that like in Kate SOFTWARE/OS VERSIONS Operating System: NixOS 23.11 KDE Plasma Version: 5.27.9 KDE Frameworks Version: 5.112.0 Qt Version: 5.15.11 Kernel Version: 6.1.63 (64-bit) Graphics Platform: Wayland Processors: 24 × 13th Gen Intel® Core™ i7-13700F Memory: 62.7 GiB of RAM Graphics Processor: AMD Radeon RX 6800 XT ADDITIONAL INFORMATION
Indeed, We can't override the basic shortcuts for Qt's text input controls here, but we can overlay our own on top ot replace them in custom subclasses, which is what apps like Kate can do. I'm afraid Qt changes would be required to be able to do what you;re asking for.
