Not a problem. I didn't think your comment was condescending, but in fact it confirmed to me that I was doing it correctly. Some descending is in order as I did mention that I'd had the unit only a week, that implies I may not be familiar with it's operation.

[Middle English condescenden, from Old French condescendre, from Late Latin condēscendere : Latin com-, intensive pref.; see com- + dēscendere, to descend; see descend.]
