Sometimes when I paste text from another app (Word or Google Docs), InDesign insists on inserting line breaks that I can not remove. Some (but not all) lines of text do not fill the width of the text box. Wehn. I try to backspace the next line to fill the empty line above, nothing happens.
In other words, I can't get some lines of text to fill the full width of the box. I've tried pasting the text without formatting, but that doesn't work either.
