I am trying to assign full screen x2go sessions to individual workspaces in MATE and then cycle through them using my DE's keyboard shortcuts. However x2goclient and pyhoca-cli eat all of my key combinations so I cannot cycle through the workspaces. In other similar software (virt-viewer) it is possible to assign a dedicated key combination (e.g. Ctrl-Alt) to momentarily stop key grabbing, after which a keyboard shortcut can be passed to the client OS. This makes it easy to assign macros to certain keys (Ctrl-Alt + Ctrl-Alt-Right to move one workspace to the right) to navigate multiple VMs in workspaces, etc. I'd like to see this functionality added to x2go. I've tried using the keystroke assigned to "deactivate_input_devices_grab" (Ctrl-Alt-y) to ~/.x2go/config/keystroke.cfg but that seems to have no effect on whether the keys are grabbed.
Strangely I have also tried setting a key combo to "ignore" in keystroke.cfg and restarted x2goserver, but it is still interpreted by my remote desktop session. So I'm not sure if this is broken altogether.
