This feature allows you to specify the maximum number of undos you can perform successively.
An undo (see chapter User Manual/Edit/Undo) cancels:
· Within a tool: The last operation performed by the current tool.
· Outside a tool: All the operations performed by the last tool used.
Management of the undos is dynamic, meaning that in most cases, it does not consume a great deal of memory (RAM). Nevertheless, do not set a large value for this parameter, especially if your system is short of RAM.
Be aware that some tools require more RAM than others, the Cut tool, for instance.
