Defining Mnemonics (Access Keys)
Normally, keyboard users move the input focus from one control to another in a dialog box with the TAB and ARROW keys. However, you can define an access key (a mnemonic or easy-to-remember name) that allows users to choose a control by pressing a single key.
To define an access key for a control with a visible caption (push buttons, check boxes, and radio buttons)
Select the control on the dialog box.
In the Properties Window, in the Caption property, type a new name for the control, typing an ampersand (&) in front of the letter you want as the access key for that control. For example, &Radio1.
An underline appears in the displayed caption to indicate the access key, for example, Radio1.
To define an access key for a control without a visible caption
Make a caption for the control by using a Static Text control in the Toolbox.
In the static text caption, type an ampersand (&) in front of the letter you want as the access key.
Make sure the static text control immediately precedes the control it labels in the tab order.
All the access keys within a dialog box should be unique.
To check for duplicate access keys
On the Format menu, click Check Mnemonics.
