Deleting, Undoing, and Redoing

Delete a box or branch

Select the box you want to delete.
Select Delete in the toolbar. On Windows, you can instead press Shift+Alt+D; on Mac, press Shift+Option+D.

Deleting a box also deletes any boxes beneath it. If you delete the main contention of a tree, the entire tree is deleted. A main contention cannot be deleted when it is the only main contention on the canvas.

Undo or redo your own changes

To undo, select Undo. On Windows, you can instead press Ctrl+Z.
To redo, select Redo. On Windows, you can instead press Ctrl+Y.

During real-time collaboration, undo and redo apply only to your own changes. You cannot undo or redo another collaborator’s changes.
