> Rewind on the kenwood does backspace; not sure which key it is on a rio remote, though I suspect it's cancel?


You're half right: rewind deletes in the numeric entry fields (year and PIN), but not in the textual ones (the ones I'm most likely to mis-type!). For those,n rewind and ffd move through the displayed search results.

Cancel returns straight to your current visual (or info) in all cases AFAICT.
