Recall Screenset 1x    ⇧1

Can never have enough references to screensets. I have entered this command before, when the command was control-1 through control-9, now it is shift-1 through shift-9. I have yet to use more than 5 or 6 screensets, only because I don’t spend enough time working on a single project to require saving that many.

Recalls screensets 10 through 19.

You position windows in a layout that suits the way you work. This layout of various windows, including their display size, zoom levels, position, and other settings, is called a screenset. Once defined, you can save, and freely switch between different screensets, much as you might between different computer displays.
