Undo many actions
Undo Many allows a number of operations to be undone or a number of previously undone operations to be redone. It is equivalent to invoking Undo or Redo multiple times.
To run this function: Choose Edit > Undo properties > Undo many actions, or...
Conceptually you can think of the software retaining a number of versions of a graphics layer. As each operation is performed the layer is modified and a new version is created. The software maintains an ordered list of these versions . When you undo an operation the version before that operation is made the current version, although the software does not discard later versions at this point. Therefore it is possible to redo an undone operation by stepping forward in this version list. Whenever a layer is modified all later versions are discarded so it is not possible to redo undone operations after any modifications are made.
Operation
The operation which you wish to undo or redo to.
Operations which may be undone are prefixed with `UNDO` and operations which may be redone are prefixed with `REDO`. The current version is represented by `CURRENT` and if it is selected no changes are made to the current graphics layer.
Use the browser to select the correct operation.
Operations for the currently selected graphics layer are undone or redone until the layer has been updated to the selected version.
