I'm using KDE Plasma on Ubuntu 18.04 and I have a very annoying shortcut: Middle click + Drag right -> Open a new instance of Konsole. It's annoying because it gets triggered regardless of the application I'm using. I can't use middle click + drag to rotate around my scene in Blender for example. How can I disable it?

P.S: It might be the case that I set this shortcut by myself in the past. I just don't remember it and looking for a way to disable it.

❯ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.4 LTS
Release:        18.04
Codename:       bionic
❯ plasmashell --version
plasmashell 5.12.9
❯ kf5-config --version
Qt: 5.9.5
KDE Frameworks: 5.44.0
kf5-config: 1.0

Update: I created a new user and it didn't have the shortcut. That actually proves that I've messed something up in my main user. I tried to look at all the settings, submenus, all the tabs of submenus but couldn't find anything relevant. Is there a program where I can tweak the settings more?

  • Did you try Right-click on the desktop-->Configure Desktop-->Mouse Actions-->Middle Button Is should be written paste, then to modify the associated command or to use the - symbol on its right to delete the action. Then Apply. Let me know.

  • @Hastur There was no middle button option. I might have deleted it before. I added it manually and set it to "paste". Nothing has changed. "Middle click + drag right" still opens up Konsole.

  • Did you add any action to "paste"?

  • @Hastur No, there are only 2 actions. Vertical-Scroll and Right-Button are bounded to Switch Desktop and Standard Menu respectively.

  • Well, then give it a try. Add an action for Middle Button, and paste and bound it to something. See if it will overwrite your previous forgotten operation :-). Good Luck. Ps> For the future do a file text with the non standard settings you modify on your computer. Memory is a limited resource on humans too.

A first note is that the OP uses plasma under Ubuntu and not under Kubuntu.
A second is that there was a manual modification in a file, the memory of which in detail was lost over time.

In general it should be possible to associate a command to the middle button paste action of the desktop via

Right-click on the desktop-->Configure Desktop-->Mouse Actions-->Middle Button. Is should be written paste and then it should be possible to modify the associated command.

In the specific OP cases it was not enough. Then the suggestion to investigate by hands the configuration files.

Before under ~/.config/plasma-org.kde.plasma.desktop-appletsrc (maybe with grep paste nomefile), under the ~/.kde directory and under .config.

Then (again) in the analogue files for Ubuntu.
The OP solved the problem with grep -e '[Mm]iddle' *rc in ~/.config: the output helped to remember a modification made two year earlier in System Settings -> Workspace -> Shortcuts -> Custom Shortcuts.

A custom shortcut called "test" which is triggered by middle click + drag right and is assigned to action "Konsole" was created. Once disabled everything turned back to normal.
