Up and down arrow symbol



Hello,
I would like to add an up or down arrow symbol while typing in a cell.
I would like to be able to use the 'option key' to insert an arrow
symbol.

1. I can add an up or down arrow symbol using 'add objects', but this
takes time and is not apart of the cell text.

2. I can add an up or down arrow symbol using 'Wingdings 3' font, but
then the cell is 'Wingdings 3' font which is no help.

3. Can I add the up or down arrow symbol to the geneva font.

Thank you,

.
