Secret commands for The Grid 1

This answer documents the "hidden" commands for The Grid 1.  These commands were added after the program was released, and so they do not feature in the manual for the software.

Unicode keys

These commands allow you to press & release keys in the on-screen keyboard by specifying their unicode keycode.  This gives access to a large set of non-latin characters.

• /keyunicodeup(KEYCODE)
• /keyunicodedown(KEYCODE)
• /keyunicodepress(KEYCODE)

Video playback

These commands allow you to play a video when a cell is added to a symbol sentence.  The /video command plays the video immediately, and the /queuevideo command stores it until the sentence is played back with a "speak" cell.

• /video(FILE)
• /quevideo(FILE)

Change user

This command allows you to create a cell that will switch to a different user.

• /username(NAME)
