The text to display in the Label.
You can define an accelerator character for a Label. In the Text property, precede the accelerator character with an ampersand. For example, the entry "&Home" signifies that the H is the accelerator. Now, pressing Alt+H on Windows triggers the AcceleratorKey event where you will typically set focus on the related TextField (or other related control).
To specify an "&" in the label text, use two in a row: "&&".
The following example sets the text of the Label.
