One more update: this handwriting recognition keyboard thing is FABULOUS! Also, you can remove the annoying screen capture button from the soft keys. Great idea, since it's pretty worthless on this tablet. So much easier to do with the pen once you figure it out!
Settings → display → quick launch gets you to where you can change the soft keys.
And I haven't the foggiest idea how to put in arrows with the regular keyboard, but with this you just draw them!
