Mnemonic

Provide a predefined mnemonic for each predefined textual choice in a menu.

Provide a mnemonic for each textual choice in a menu, unless you cannot find a meaningful unique mnemonic.

Provide a mnemonic for the group heading associated with a tab group.

Provide a mnemonic for the label associated with a text field.

Provide a mnemonic for each push button with a textual label.

Provide a mnemonic for each radio button and check box with a textual label in a tab group.

Make mnemonics unique among all choices in a menu.

Make mnemonics unique among all radio buttons and check boxes in a tab group.

Make mnemonics unique among all push buttons, group headings, and menu-bar items.

If a mnemonic is an alphabetic character, allow the user to press either the uppercase or lowercase character.

The character used as a label's mnemonic must appear in the label and be highlighted within it, generally by underlining it.

If choices are duplicated within an application, assign the same mnemonic to the choices.

For textual labels that do not have a mnemonic defined, assign mnemonic characters by applying the first applicable guideline that follows:

A group of labels that require unique mnemonics may have their mnemonics generated by sequentially assigned numbers or letters to the labels, prepending the uniquely assigned character to its corresponding label (along with any bracketing or separator characters) and underlining it.

When the active cursor is in a menu and the user types the mnemonic of a choice within that menu, move the cursor to the choice and activate or toggle it.

When the active cursor is in a tab group and the user types the mnemonic of a choice within that tab group, activate or toggle the choice. If an explicit focus policy is in use, move focus to the choice.

When the cursor is in a window or a spring-loaded system popped up or cascaded from that window, and the user presses Alt plus a mnemonic associated with a control in the window, activate or navigate to that control after first deactivating any spring-loaded system that contains the cursor. For more information, see Alt Mnemonic Behavior.

When the user presses Alt plus a mnemonic associated with a menu-bar item, activate that menu-bar item and move focus to the menu pulled down from it.

When the user presses Alt plus a mnemonic associated with an option menu or menu cascade button, pull down the corresponding menu and move focus to it.

When the user presses Alt plus a mnemonic associated with a push button, activate the push button. If using an explicit focus policy, and the focus is not in the data area affected by the push button's action, move focus to the push button.

When the user presses Alt plus a mnemonic associated with a text field or tab group (other than for a control described previously) and an explicit focus is in use, move focus to that tab group or text field.
