Note the errors in the previous post: an extra "an," too much punctuation at the end. Those resulted because I cannot seem actually to delete anything once typed: neither on initial entry or upon subsequent editing. (Perhaps a limitation of Safari? To be checked out.) And all the garbage at the end of the post — that's the result of what I had to do to fix a typo, namely put the cursor in front of it and leave it in place, to accumulate at the end.
