This allows you to type a command key to select buttons in most modal dialogs. A modal dialog is a window that beeps when you outside it. For example, most file selection windows and alert alert messages use modal dialogs. 

	When a modal dialog is displayed, you may hold down the command key and type a letter and Button Keys will try to find a button whose name starts with that letter. If there is such a button, then it is pressed, exactly as if you had clicked on it with the mouse. If there are two or more buttons whose names begin with the letter, then one of them will be pressed, but there is now way to determine which.

	For example, when you want to open a file, most applications create a dialog that allows you to select a file. This dialog typically has a Cancel button. If Button Keys are running, you may type command C instead of clicking the mouse over the Cancel button.

	When you hold down the shift and command key and type a letter, Button Keys will try to find a checkbox or selection item whose name starts with that letter. If there is such a checkbox, then it is pressed, exactly as if you had clicked on it with the mouse. If there are two or more checkboxes whose names begin with that letter, then one of them will be pressed, but there is now way to determine which.

NOTE: A few applications offer similar command key shortcuts for their windows and these may effect checkbox items even when you are not holding the shift key.
