Keyboard shortcuts missing in Gnome

In 15.6 Gnome, … some shortcuts are missing:

Move window one workspace down
Move window one workspace up

In addition, there appears to be no way to add a custom shortcut.

How does one add them in 15.6?

TIA!

Have also a look under the Tab “Predefined shortcuts-> Navigation” in the linked article…

As there are no workspaces “up” or “down” anymore (but in a horizontal row), these two shortcuts seems to be no longer necessary.

Instead the two shortcuts “Move window one workspace to the left Shift+Super+Page up” and “Move window one workspace to the right Shift+Super+Page down” are available and enabled by default.

Not really, what happens with three or four monitors?? Horizontal moves don’t work, as that limits the workspaces to physical monitors.

Not there in 15.6, … neither is a way to ADD them!

Looks like the valid Gnome navigation options are listed in gsettings:

gsettings list-recursively org.gnome.desktop.wm.keybindings | grep move-to-

For example, here are valid commands for up/dn:
move-to-monitor-up
move-to-workspace-down

A custom shortcut using these valid commands will create a new shortcut.
