No-Key-Letter
When this style is set, all "&" characters found in the title are treated as any other letter.
When this style is not set, the first "&" character in the title is not displayed; the next character can used, in conjunction with the [Alt] key, to activate the Label control. This is the default setting.
 
Example - Define a label that includes the & as part of the title
screen section.
