the keybinding which can be used to activate this action, or %NULL if there is no keybinding for this action.
"n" in a traditional "New..." menu item or the "a" in "Apply" for a button. - The sequence is the full list of keys which invoke the action even if the relevant element is not currently shown on screen. For instance, for a menu item the sequence is the keybindings used to open the parent menus before invoking. The sequence string is colon-delimited. Example: "Alt+F:N" in a traditional "New..." menu item. - The shortcut, if it exists, will invoke the same action without showing the component or its enclosing menus or dialogs. Example: "Ctrl+N" in a traditional "New..." menu item.
For a traditional "New..." menu item, the expected return value would be: "N;Alt+F:N;Ctrl+N" for the English locale and "N;Alt+D:N;Strg+N" for the German locale. If, hypothetically, this menu item lacked a mnemonic, it would be represented by ";;Ctrl+N" and ";;Strg+N" respectively.
Gets the keybinding which can be used to activate this action, if one exists. The string returned should contain localized, human-readable, key sequences as they would appear when displayed on screen. It must be in the format "mnemonic;sequence;shortcut".
- The mnemonic key activates the object if it is presently enabled onscreen. This typically corresponds to the underlined letter within the widget.
