Scenario which newly created or modified has to be saved.
In order to save a scenario, click "Documents / Save" of the menu (or type Command-s).ToyProjector can open more than one scenario document at the same time. In order to save them at once, click "Documents / Save All" of the menu.
You can save opened scenarios as other name. However, there is a restriction. New file should be saved in the same directory in which the original file is created, or in its ancestor directory. The reason of this restriction is that files in a scenario are specified with relative paths.
In order to save a scenario as other name, click "Documents / Save As..." of the menu.
In order to open a scenario file, double click its icon on File Viewer, or click "Documents / Open..." of the menu.
In order to cancel modification on the scenario and to revert to a previous saved state, click "Documents / Revert to Saved" of the menu.
