A window snaps within its own display, not the one your pointer happens to be on.

Rebinding

Click a shortcut in Settings ▸ Shortcuts and press the combination you want. Esc cancels.

If the combination is already used by another Orthant command, the row tells you which one and asks. Press the same combination again, or click the button beside the question, to take it. The command that lost it becomes Not set, and an Undo appears for ten seconds.

Some combinations belong to macOS itself. Those are marked in the list rather than silently failing to fire.

Resetting

Reset Shortcuts puts every built-in command back to the defaults above. Custom regions survive a reset; their shortcuts do not. An Undo appears afterwards.
