Unable to set hotkeys for workspace switching vertically using both modifiers (maybe just a functional problem now, hotkeys were fine)

edit

I guess I will have to go through dconf-editor (not gconf-editor for some reason, w/e).

Finally found the keys as strings under org > gnome > desktop > wm > keybindings : switch-to-workspace-_____. Editing values around by looking at the other presets seems self-explanatory, example: move-to-workspace-left = ['<Control><Shift><Alt>Left']

Updates:

Strangely enough, the move-to-workspace-_____ keys seem to be dual-set to my liking already.

Looks like the keys for moving to workspaces above and below are also dual-set to my liking too, but only the first is reflected in the gnome-tweak-tool misleadingly, maybe as to why I cannot change to that key combination, as it is already set to that property.

The hotkeys do not work using the arrow keys, only the Page- keys. This may be a slightly different issue now. The situation does not improve, even if I move the string for my preferred Ctrl-Alt key combination as the first item in the string array for each property.

Also, I am able to set hotkeys using both of my preferred modifier keys now. I do not need to do this for the properties I need to work with, but I tested this in a custom shortcut just to be sure I could.

Now my problem seems to just getting the switch workspace function to work with the arrow keys..

I found that by checking "Auto Capture Keyboard" under File -> Preferences -> Input, this allowed me to switch workspaces. ( https://forums.virtualbox.org/viewtop... ) I will probably use this as an answer now, but I cam still curious as to what interaction is directly preventing this. Maybe it's as convoluted as the way Windows recognizes multiple modifier keys for input, and changes its own 'mode', but that doesn't translate as inputs to the VM? Don't know; that was just a speculation.
