If I then repeat this to highlight the  text in the categoryComboBox by repeating the code, titleComboBox gets deselected and categoryComboBox gets selected.  I want to highlight them both simultaneously.  I'd also rather use the big yellow highlight like with the find panel (but that's later).

Your code will not work because there can be only one active field editor at a time, and you are controlling the text by manipulating the selectedRange property of the field editor.

I would be inclined to try using attributed strings to show the selection. Maybe something like this:

if (r.location != NSNotFound) {
	NSMutableAttributedString *stringWithSelection = [[NSMutableAttributedString alloc] initWithString:s];
	[stringWithSelection addAttribute: NSBackgroundColorAttributeName value:[NSColor yellowColor] range:r];
	// set control value to stringWithSelection, using whatever technique is appropriate
	[stringWithSelection release];
}

To deselect, just set the control value to [[control attributedStringValue] string].

There are other ways to do what you need. This might be the most straightforward.
