When you reset an Action, a Modular Keyer, or a Keyer node, the undo list is cleared. When an Action, a Modular Keyer, or a Keyer node is part of a branch in a process tree, you may accidentally clear the undo list when you reset these or other nodes. To prevent the accidental clearing of the undo list when you reset any of these nodes, a warning appears and you are prompted to confirm. For example, when you click Reset to reset a Colour Warper node that is parenting a Keyer node, you must confirm.
