Something you could try is using the scratch pad. Either copy and paste, or drag and drop the desired text snippits into the scratch pad. When you have everything added to it that you desire, use the Destination drop-down to create a new document with the contents. The Scratchpad can be safely cleaned out at that point.
Well, I could see the utility in what I think Birdonbook has suggested.
If one was writting a book over many months, highlighting compose text for one reason or another - things that still needed to be researched, text that might be used for promo purposes, grammer questions, etc. - at the end it would be nice to gather all this highlighted text (by any or all highlight colors) into a seperate document, rather than stepping through searched for highights, then cutting and pasting them into such a document.
Using command key I did what you say inside a sentence:
“Once upon a time there was a software whose name was Scrivener”
I select words “there” + “was” + “Scrivener” and copy them.
Why, when I paste them, are they separated by a return and not a space?
Don’t you think it would be more practical…
