SUMMARY I have only tested this with the Clipboard (Klipper) application so far, which is where I intended to use the keyboard shortcut, but whenever I set the following shortcut: CTRL + SHIFT + | (§-key on my keyboard layout), then it would prevent CTRL+S (save, default) from functioning whatsoever. The moment I disabled the keyboard shortcut again, the problem went away. I am using a Norwegian Bokmål keyboard layout that is built-in to Kubuntu. STEPS TO REPRODUCE 1. Opening Klipper settings (Configure Clipboard) 2. Assigning keyboard shortcut CTRL+SHIFT+| (it will print CTRL+§ as a result) 3. Opening up Visual Studio Code or Kate to test, and unable to use CTRL+S. However, CTRL + SHIFT + S works as intended (Save as). OBSERVED RESULT The problem disappears whenever I remove this keyboard shortcut, or choose a different one. CTRL + | for example works just fine. So for some reason it is mixing the § sign with S(?) EXPECTED RESULT That it records CTRL+SHIFT+| instead of using the shift function on the letter SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Kubuntu 20.10 (64-bit) (available in About System) KDE Plasma Version: 5.19.5 KDE Frameworks Version: 5.74.0 Qt Version: 5.14.2 ADDITIONAL INFORMATION If you need any additional information, feel free to get in touch.
Corrected product* Sorry about that.
Please try the behavior on Wayland. Also, try US layout. AFAIK, it records Shift modifier for letter shortcuts only (I didn't check it). In your case nor | neither § are probably letters, so maybe CTRL+§ is normal.
