Making Mistakes and Experimenting

If you are going to try to add something that you're not sure will work, first use Save As to rename your file to another version. For example if you are working on scape.bmp then you may change this to scape1.bmp and so on with later versions. This will allow you to go back to a previous file if your experiment doesn't look as good as you had hoped.

You may Undo your last action by using the Control-Z key combination. (Hold down the Control key and press the Z key) You may undo actions up to 3 times but no more. Going further "back" is only possible if you have an earlier version of your work, as mentioned in the previous paragraph.
