Undo the Last Operation with your Mouse - MS Paint Trick

Undo the Last Operation with your Mouse - MS Paint Trick

MS Paint supports 3-level of undos meaning that you can only undo the last 3 changes made to a drawing. You can however undo (or rather cancel) the last operation using the right button of your button.

For instance, if you have selected the freehand tool to draw a line but if the line doesn’t meet your expectation, don’t let go the left button and click the right-button to cancel the last operation. This will save you from using the keystroke CTRL+Z to undo your last stroke and won’t add anything to your undo stack.
