No, you will probably need to zip-compress the folder. For example on the Mac, you would right-click (or ctrl-click with a one button mouse) and choose Compress from the pop-up context menu. That will turn the whole folder into a .zip file that you can upload. In Windows, you do something similar, like right-click and choose “Make zip archive” (I can’t remember the wording exactly).

Tell your instructor that I say you should get extra credit because you were smart enough to come to InDesignSecrets to ask. :-)

I’m not going to recommend or advise on this, but I think LightningSource can handle it:

You can also try Lulu.com or perhaps amazon’s Createspace

I wonder if this old post would help:

There’s no way to do it truly randomly with GREP. You could create a findchangebylist.jsx file that would replace all “e” with “r” and all “T” with “A” and so on, but it would do the same thing for all letters. It would appear random, but wouldn’t be.

That might be enough to satisfy your client, but a codebreaker would be able to decipher it pretty easily.

Sorry, I’m not clear on what you’re trying to find. But I think the answer is: Put what you’re looking for in parenthesis, and then use $1 to call it back up.

For example, look at the “Fun Tricks” section here: https://creativepro.com/favorite-grep-expressions-you-can-use.php

You can put a “bullet” at the end of the line, but you can’t do it at beginning and end.

You could sort of fake it with something like this, perhaps:

Or you could set up the table of contents style to “disappear” the quote marks. So they would be there, but you wouldn’t be able to see them.
