All shortcuts can be assigned/reassigned at edge://extensions/shortcuts in Edge.

Notes:

If a tab runs off the edge of the screen, it wraps back around to the start.

Pinned tabs are fully supported.

If an ungrouped tab is moved around:
- with the single tab shortcuts, it will naturally join and unjoin tab groups as it runs into them
- with the tab group shortcuts, it will skip around any existing tab groups
