Mnemonic property

This is where you may, optionally, specify a letter that can be used as a mnemonic. This letter must be one of the letters in the prompt for the menu line (preferably its first letter). The letter you type will be underscored in the menu line. Together with the ALT key, this mnemonic will activate the menu option if it is in the toolbar. Without the ALT key, the mnemonic will activate the menu option if the corresponding menu page has already been activated.

If you do not specify a letter to be used as a mnemonic, USoft Developer will allow using the first letter of the first word of the menu line as a mnemonic (but only if that letter is a unique first letter on the menu page).
