Created attachment 144947 [details] AltSearch – shortcut creation instruction Latest release installed successfully (v.1.4.2, released Mar 24, 2017).

*** This bug has been marked as a duplicate of bug 38261 ***
How is this a dupe of 38261? Also, reporter - can you clarify how the Ctrl+F10 functionality (which makes formatting marks visible) relates to what you want to do with the F&R dialog?
(In reply to Eyal Rozenberg from comment #4) > How is this a dupe of 38261? From the description it sounds like the goal was to replace paragraph ends with spaces, which is typical in various cases like cleaning up content copied from PDFs or emails.
