Seems like a radio button format might make more sense when the possible values are yes and no.
A script trigger can be used to do your "touch the background" step automatically. I'd change your format to either a radio button or pop up menu, then use the OnObjectModify trigger to perform this simple script:
Phil, that worked great!
Now, is there a way when searching on an ipad to skip the popup that tells you how many records are found?
Hmm, that's a new one on me. I don't have an iPad but finds on my iPhone aren't popping up any such dialog. But then my scripted finds always enable set Error capture so maybe that is the difference?
If all else fails you might set things up so that Go To Related Records is used in place of a scripted find.
