Paint Tool SAI is a great program, but some of the conveniences aren't always obvious. If you have questions about any of that, please try the SYSTEMAX website (developers of SAI, now on version 1.25), or SAI in English Forums. I also can't help you with issues using SAI surface pro or OS related problems, either.
I haven't used SAI for almost eight years, now, and can't answer technical questions about issues outside shortcuts.
I can't answer questions about later versions as I don't have them. This tutorial is for version 1.1.0 of SAI.
