|
The Undo and Redo commands enable to step back or forward in already taken actions.
|
|
Each executed command in FASTSUITE Edition 2 will be stored in an internal list. With the Undo command it is possible to step through that list starting from the last executed operation down to the last one in the list. Of course in the same order as how the operations have been executed initially, but then in reverse direction. When stepping downward this list with the Undo actions, it will become possible also to step upward again. For that the Redo command then has to be applied.

|
The following example below shows the effect of the Undo and Redo commands:

|
|
|
It has to be understood that the list of executed operations will always be extended from the last current position in that list.Thus when the user steps back in the list with a number of Undo actions and then continues his work with a new command, this new command becomes the next entry in the list. All previously possible Redo steps then no longer are available.

|
|
Keep in mind that at every change of Workbench all entries on the internal list of Undo and Redo actions are deleted. The list will be blank and recreated at the start of the newly opened Workbench..
