Efficient Undo/Redo:
|  | Click to undo/redo Maya operation. The beauty is that it can step through the null undo/redo and undo/redo many steps by one click. More option can be found through the option box.
How to call it ( Do one of the following ) : ▪Right mouse button clicking on the button of MGTools,select "EfficientUndo../EfficientRedo.." ▪Click the icon in your Maya shelves (If U have installed all the MGTools shelves into Maya shelves) .Invoking by this way will only able to undo/redo one step. ▪Click the EfficientUndo/Redo button of the miniToolBox. (or the option box on the right side of it.) When to use it: 1.Want to undo/redo quickly,or the steps need to be undone are too many. 2.Sometime after clicking the playback button in Maya,it ends up with great mount of nonsense undo steps. If U want to undo a real step,U got press z crazily,vice verse. The Option Box: The undo redo option shares the same UI. Change operation between undo & redo,the UI element will be updated correspondingly . Here we take undo as example: Undo Times: How many undo steps will be done through one click on the "Undo!!" button of the right corner. Auto-StepThrough Null Undo： When doing undo, if it meets a non-sense undo, it will keep undoing until it meets another undo that makes sense. this option is grayed out because nobody want to do non-sense undo one by one.. Auto-StepThrough Undo With Name：When this option is checked on, input a undo step name.then every time this tool meets the right name, it will automatically step it through. Query button: Query current undo name and fill the name into the textField left. Undo!!: Undo by the options been set. Notice: Unlike maya's optionBox, this option box setting wont be remembered and wont affect the acting of the Efficient Undo/Redo button on the minitoolBox .
