Undo and redo
Ctrl+Z undoes the last edit. Ctrl+Shift+Z or Ctrl+Y redoes it.
What a step is
Section titled “What a step is”One gesture is one step: a continuous brush stroke, a drag, a paste, a bulk action. Undoing in the middle of a stroke ends the stroke, and the rest of the drag does not paint over what came back.
Creating, renaming and deleting respawns, houses, towns, waypoints and zones are also steps.
Limits
Section titled “Limits”The history keeps up to 100 steps per session, and at most 400,000 tiles in total. Past that, the oldest steps drop out. Reloading the page clears the undo history.
Viewing the steps
Section titled “Viewing the steps”In the right panel, the clock icon opens the history. The Edits in this session section (Edições desta sessão) lists the steps, newest first, with Undo and Redo buttons. Each step shows what changed (fields, respawns, waypoints, zones, houses, towns); undone steps show as “undone”.
Below it, the Versions section lists the publications. See Collaboration.
Undo and publishing
Section titled “Undo and publishing”The footer of the layers panel shows “N unpublished changes”. Undoing does not count as a new change in that number. See Publishing the map.
