Hello, I have 2 questions

1. for an existing drop down list, how can I add a new entry? That is, a
list named "division" now contains 5 items, and I want to add a sixth. I've
tried to highlight all 6 items and typing "division" into the name box, but
that just jumps me to the original 5 names. I also tried highlighting the
original 5 and deleting the "division" from the name box, but again no luck.

2. Can I enlarge the font on a drop down list, so it appears larger when
the arrow is clicked? The font is very small at present.
