Well, I did click the “X” at the bottom, exactly as instructed. Then I went on to the next step/document. I am only reporting what I saw, but I am pretty sure I didn’t leave out a step.
Thanks for the tip about removing the highlighting. I will try it.
I’ll start working through the next section shortly.
Here is something else by way of feedback, tangentially related to the tutorial.
A few weeks ago, my friend (and co-NaNo nut) tried to import her files for her WIP into Scrivener, and could not get it to work. I scratched my head and spent some time here on the forums trying to find an answer, to no avail. I think I also consulted the PDF manual, but am not certain. We never did figure it out, and since she had about 70 files she didn’t want to go through each one and do a copy/paste.
Well, going through the tutorial just now, I came across the following parenthetical note:
“Note that if you have selected a document that is contained inside the “Draft” folder in the binder, when you go to File > Import > Files… you will only have the option of importing text file types. . .”
followed by:
“You can also drag files directly from Windows Explorer into Scrivener’s binder and drag them out again to export.”
This was the solution. She was able to import about 50 files in one dragging operation, which made her VERY happy (and me too, to have found the answer!); however, none of the Open Office ODT files imported. (Why is a separate question.)
I am offering this mostly by way of feedback. I was completely stumped and eventually gave up, concluding that it was a bug and/or something not yet implemented (this was before I registered on your forum). Not sure what you can do to make it more clear. Perhaps a note on the import dialog box explaining the text file limitation?
And what is the deal with Open Office ODT files?
Final bits:
Other Stuff
“and if you like where things are going you can press Ctrl-S to save and continue one.”
I think that should be “continue on” (not “one”).
Scratch Pad: this sounds interesting. Where/how do I access it?
Final, final bit: All the various buttons should have tool tips, at least of their names. I still do not know what some of the buttons in the toolbar do, or some of the icons/buttons at the bottom of the screen in the binder and inspector.
Edited to add: I just discovered that they all apparently do have tooltips, but I cannot isolate what set of circumstances makes them appear. They worked once when I opened and closed the inspector, but they no longer seem to be working. I expect something like tooltips to be completely independent of the cursor’s location. To me, this makes the tooltips useless, and frustrating, because whether an item had a tooltip or not seemed random (now I know that they all have them, so it’s just getting them to show up that’s random).
This is similar, I think, to the problem my friend and I had trying to import her files. I expected for the files to import where the cursor was in the binder, and it makes no sense to me (even with the explanation in the tutorial) that the cursor’s location in the binder would restrict the filetypes available for import.
I realize this thread has drifted far from its original subject, but it didn’t seem worth the trouble to start a new thread for each item. Hope that’s okay. 
Thank you for all of your hard work!
