Menu Items / The Level Menu
	The Level Menu, which is only active when the Levels Window is open, is used for creating and deleting game levels, and for displaying and modifying the contents of the current level. The following commands appear in the Level Menu:
Create New Level...	Creates a new level. When creating a new level, you are given the option of creating a new empty level, or creating a new level that is based on one of the already existing levels in the current game project.
Delete Level...	Deletes the current level. When a level is deleted the connections between the remaining levels are automatically reestablished. This process may take a long time.
Show Solid Material Mask	Displays an overlay indicating which parts of the level are comprised of solid material and which parts of the level consist of empty space. (Generally characters and objects in the level are not permitted to pass through solid material.) When this command is selected a checkmark appears next to the menu item. Selecting this command again hides the solid material overlay. Keyboard Shortcut: Command-G
Show Parallax Layers	In a level with a normal, non-tiled background, this command displays the parallax background, which often consists of two or more layers scrolling at different speeds, creating a sense of depth. (Tiled backgrounds may not be parallax.) When this command is selected a checkmark appears next to the menu item. Selecting this command again hides the parallax background layers and displays a single background layer. It is important to see what levels look like both with and without parallax layers because the player may turn parallax scrolling on or off in the game's preferences. (If this command is disabled and the level does not use tiles, it is likely because Mask Mode is enabled. Switching back to Objects Mode should enable the Show Parallax Layers command.) Keyboard Shortcut: Command-P
Edit Level Parameters	Opens the Level Parameters Window, which includes controls for editing the level's intro and ending pictures, music and sounds, level-triggered routines, and additional properties. Keyboard Shortcut: Command-L
Edit Level Routines	Opens the Level Routines Window, which is used to create Routines. Routines cause actions to occur which can change the state of the level or its inhabitants, leading to advanced game mechanics. Keyboard Shortcut: Command-E
Normal Mode	Switches to Normal Mode, which is used to manipulate objects in a level. This is the most commonly used level editing mode. Keyboard Shortcut: Command-Y
Mask Mode	Switches to Mask Mode, which is used to edit a level's Solid Material Mask, which determines the location of solid matter and empty space within the level Keyboard Shortcut: Command-U
Tiles Mode	Switches to Tiles Mode, which is used to edit a level's tile background. This option is only enabled if the current level uses a tiled background. Keyboard Shortcut: Command-I
