Force First Line of Justified Paragraph to be Flush Left
I'm using InDesign and I want to justify a paragraph, but the first line (the title of the paragraph) has to be aligned left.
The simplest solution is to break this into two paragraphs -- a heading paragraph followed by a body para. But it sounds like you want them to be a single paragraph for some reason so? here's a solution: Follow the heading with a tab and then a forced line break (Shift-return/enter).
For example, here's the original paragraph:
Now, here's what we get when we put a Shift-Return/Enter (forced line break, or "soft return") after the period instead of the space:
That obviously isn't going to work! But if you put a tab character after the end of the heading (before the soft return) you get what (I think) you want:
You don't need to set any tab stops or anything like that; the tab character itself is all you need.
Note that the bold heading could be formatted manually, but in this case I'm using a nested style or a line style inside the paragraph style.
I wish there were a way to automate this trick in a paragraph style, but you have to manually insert the tab character. (You might be able to find a way to insert it quickly with a find/change, though, depending on the formatting of your headings.)
