Battery Change - Configuration Pointers

I’ve never changed a battery in any of my computers and am about to do
so in my Dell 8300. Instructions directed my to make note of the
computers configuration (using the F2 routine). I’ve done so but
having never altered any of those settings, I want to make sure I know
what to expect when it’s time to reset them after the battery is
replaced. The settings look self explanatory but I’d feel more
comfortable if I run this by a few who’ve been there before me just in
case there’s something I’m overlooking.

I’ve numbered the lines of the configuration for easy reference. I’m a
tad confused on a few of these. For example, lines 4 and 5 have
notations at the bottom of their pop-ups: “+, - to move down/up”.
What’s that all about? The down/up arrows work and leave far less to
the imagination. Or are these characters to be used if I click
“enter”?

And how about 7a? Not that I want to but, how does one change from
“Enabled” to “Disabled”? There were no “+, -“ notations to indicate
some change was possible. Of course… I left this setting alone, but
will it change when I loose power? If so, how do I change it back to
“Enabled”?
