SUMMARY keyboard shortcut ctrl-B fails to do anything STEPS TO REPRODUCE 1. Start konsole, type a line for a bash command, and use standard bash shortcut ctrl-B to try to move cursor one place to the left 2. 3. OBSERVED RESULT Nothing happens EXPECTED RESULT cursor should move one space to the left SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.18.4.1-2in arch linux (available in About System) KDE Plasma Version: 5.18.4.1-2 KDE Frameworks Version: 5.69.0-1 Qt Version: 5.14.2-1 ADDITIONAL INFORMATION The other similar keyboard shortcuts ctrl-F. alt-B and ctrl-B all work fine
That's because Ctrl+B clashes with KDE standard shortcut "Add Bookmark" (systemsettings -> shortcuts -> standard shortcuts); if you change it via systemsettings to anything else it should work in Konsole/Bash. I see this in the code: https://cgit.kde.org/konsole.git/tree/src/MainWindow.cpp#n197 but I don't see the "add bookmark" action in the keyboard shortcuts editor in konsole, so something has changed at some point.
I can confirm that after a system upgrade ctrl+b no longer works in konsole. Downgrading konsole does not fix this problem. One has to manualy unbind the 'add bookmark' shortcut to fix this.
