reversible actions
any action that can be undone. Reversibility is a design principle that says people should be able to recover from their inevitable mistakes. Dialog boxes should have a Cancel button. Applications should have an Undo feature (and possibly multiple undo, and Redo).
Actions that are not reversible (e.g. saving over a file without making a backup) should require a user to explicitly commit to them.
