Summary
Sets or gets the type of processing that is performed on a string when the hot key prefix, an ampersand (&), is encountered.
Description
Use this property to set or get the type of processing that
is performed on a string when the hot key prefix, an
ampersand (&), is encountered. The ampersand is called the
hot key prefix and can be used to designate certain keys as
hot keys.
Remarks
Hot keys, also called access keys, are keys that are
programmed to provide an end user with keyboard shortcuts to
functionality and are activated by pressing the ALT key. The
keys are application dependent and are identified by an
underscored letter, typically in a menu name or menu item;
for example, when you press ALT, the letter F of the File
menu is underscored. The F key is a shortcut to display the
File menu.
A client programmer designates a hot key in an application by using the hot key prefix, an ampersand (&), in a string that typically is displayed as the name of a menu or an item in a menu and by using the SetHotkeyPrefix method to set the appropriate type of processing. When a character in a string is preceded with an ampersand, the key that corresponds to the character becomes a hot key during the processing that occurs when the string is drawn on the display device. The ampersand is called a hot key prefix because it precedes the character to be activated. If HotkeyPrefixNone is passed to SetHotkeyPrefix, no processing of the hot key prefix occurs.
Note The term hot key is used synonymously here with the term access key. The term hot key may have a different meaning in other Windows APIs.
