This command provides a quick way to save a design under a new name. The program adds a caret (^) and a number at the end of the current file name, before the .kit extension.
For example, the design name mydesign.kit becomes mydesign^1.kit. This command can be useful when saving different phases of a design; you can undo the latter steps without having to restart the entire layout.
The fastest way to save an incremental design is to press the CTRL+L keys. You can also choose FILE, Save as, Incremental Save.
