UI_PKEY_Label is used by an application to query the label text of tabs, groups, buttons, gallery items, and other Ribbon controls.
Note Windows 8 and newer: Application Menu button image changed to label: File. We recommend that you do not use File as the label for any of your own tabs.
The property value is a string constrained to any sequence of characters, including white space and line-break characters.
Note Use the Universal Character Set (UCS) XML character reference
to specify a line break.
Right alignment is not supported.
The maximum length of UI_PKEY_Label is unbounded.
If a Command is exposed through a menu item and the value of Command.LabelTitle or UI_PKEY_Label contains a letter preceded by an ampersand, as shown in the following example, this letter is treated as both a keytip and a keyboard accelerator for that Command by the Ribbon framework.
<Command Name="cmdNew" Symbol="ID_FILE_NEW" Comment="New" Id="25001" LabelTitle="&New"/>
To display an ampersand in a label, escape the special character designation with a
double ampersand (
&&) as shown in the following example.
<Command Name="cmdOpen" Symbol="ID_FILE_OPEN" Comment="Open" Id="25002" LabelTitle="&&Open"/>
