If you press the ? when a keyword is under the cursor then topical help pops up. If you are on a blank line and press ? the the whole document opens up. There's stuff in there about using reserved keywords like HARDWARE to query the system. Also shows how to load programs into the various code pages. A lot of info that isn't really anywhere else. It's a good read.

You can download an official pdf of the instruction set, or read the page online. There's also a pdf manual there.
In-game you can push the ? on the keyboard to access the inline help, there is good info on new system festures there. It's different than the home button manual.
I got Petit Computer on the day I got the N3DS...What a great program! Ranks right up there with SSB4 & MH4U as my most used software. Keep up the great work. I Will buy any future versions the day of release, without hesitation.
