I use the Find utility quite a lot. I’m using Scrivener 1.54 on Mac OS X 10.6.5.
When I enter the string I’m looking for, the string (if found) is highlighted in a bright yellow, making it easy to find. But fades to a gray background quickly. Is there any way to keep the bright yellow until I do something else. I can’t always see the gray!
I don’t believe there’s a way to keep that pop-out yellow box, but if you switch the focus to the editor itself, the search string will appear in your regular “selected text” highlight color, rather than gray (since it is, in fact, selected), and you can use cmd-G to skip to the next instance of the search query (and cmd-shift-G to go back). Maybe that helps a little?
Also, depending what you’re searching for, if you use the project search bar up in the top right of the window, that will put all your search text in a persistent highlight color that you can set in Scrivener>Preferences>Fonts & Colors.
Thank you! I think I was already in the Editor, but using the Project search bar does a better job for me than the find utility!
Okay, I should have tried it before responding. I like the project search bar because it allows me to see all the occurrences of my search strong within the page. But I have to keep inputting the search strong over and over because every time I make a change, the highlighted words lose their highlighting. For example, I’m searching for “not” so I can make contractions where needed (change “cannot” to "can’t’). Each time I make the change, the highlighting goes away.
Oops, I forgot that one. Go to Scrivener>Preferences>Text Editing and toward the bottom under Editor Options deselect “Editing clears search highlights.” 
That’s wonderful! Thanks!
