Presets for commands, allows to define command types and their handlers. A preset maps from a JSUndoManagerCommand2 to a JSUndoManagerCommand1.
To add a preset, simply set it on this object, or using Object.assign.
Bind 'undo' and 'redo' actions to 'Ctrl/Cmd+Z', 'Ctrl+Y' & 'Ctrl/Cmd+Shift+Z' hot keys. It is a basic implementation for quick testing and should be replaced with custom event handlers for more flexible processing.
