Undo and redo history

The undo/redo history is held on a per-form-window basis, up to a user-definable maximum number of actions. The default is 20.

These actions are supported by the Undo/Redo History feature:

• Control creation
• Control deletion
• Form window property modification (via the property browser or via resize)
• Change control type
• Control reparenting
• Tab page/grid column reordering
• Tab order changes
• Form permission changes
• Form help changes.
