The Print Button Name appears as a text label on the Print Button.
To set a Hotkey for a Print Button, insert the "&" (ampersand) character directly before the letter in the Name to designate it as the Hotkey.
For example:
&Receipt identifies the R as the Hotkey.
If a Sales Transaction's Print Button list includes a Receipt button with the "R" defined as the Hotkey, the [R] key may be preseed to select that button.
