Intellij IDEA move element left/right (Ctrl+Alt+Shift+Left/Right) doesn't work on Ubuntu 18.01

Question

It seems that ( Ctrl + Alt + Shift + Left / Right ) hotkey is used by Ubuntu, so IDEA can't pick it up.

After googling I found out that these hotkeys are assigned to move-to-workspace-right and move-to-workspace-left Ubuntu actions. But when I disabled those (set [], or ['disabled']) in Ubuntu, IDEA still can't pick this hotkey up.

Could anyone help to find out what other actions can be bind to those hotkeys or how can I get a list of all used keybinding in the Ubuntu. (I can't find them in the default Ubuntu settings and gnome tweaks)

Move-to-workspace-right and move-to-workspace-left is shown only in dconf tool.

Answer 1

For my case, all Ctrl + Alt + Alt hotkeys were disabled in the system. From my understanding, this is due to the fact that the keys for switching layouts intercept these combinations.

I solved this problem by resetting the default mapping options. Settings -> Devices -> Keyboard -> Reset All... .

At the moment I do not know how to save the keyboard switch combination, but there is a thread about it: https://askubuntu.com/questions/1029588/18-04-ctrlshift-to-change-language

This answer looks pretty good enough.

Answer 2

I finally found the problem.

Along with disabling both move-to-workspace-right and switch-to-workspace-right ; move-to-workspace-left and switch-to-workspace-left hotkeys, need to be sure that Gnome tweak tool > Switching to another layout does not use any of Ctrl Alt Shift .

For example, when switching to another layout hotkey is Alt + Shift , it means that all other hotkeys Alt + Shift + Any key will be unavailable.

Answer 3

It's out of my mind but combination Ctrl + Alt + Super + Shift + Left / Right works for me.
