Assuming that joeagreen knows how to operate a computer (& mouse) I would
think that he would know how to do that already.
What I think he's asking about is the "Highlight" functionality in Word
(where you can change the background color for a portion of the text, as
opposed to the whole text box) and not just "selecting" text. Putting
lines/rectangles behind the text just doesn't cut it, because they won't move
with the text (if you adjust width of the box, font, size, etc.) and they
require some effort to look right.
When searching for "highlight text in Publisher" the first page of results
is full of mirrors of a similarly unhelpful response from you which basically
just says "Publisher doesn't need to do that because most people won't
complain about it not being there" and suggest using Word instead. But Word
doesn't have as much control (setting guides, etc.). Now I need to determine
which will be "least worst": deal with it in Publisher, try Word, or look
into one of the shareware DTP programs that actually does have this
functionality (like Publisher Pro 2.0).
I know you have no control over the feature set of the application, but the
"official Microsoft" response is frustrating because it makes it sound like
MS hasn't deemed it necessary to add any functionality into Publisher. You
get what you get, and don't throw a fit...
