The TButton component has a property called Cancel. When you set this
property to TRUE for a specific button, when the escape key is pressed
then that buttons OnClick event is also called.

I have a (modal) form with a number of controls on it. I'd like to
quit the form (with mrCancel) when I press the esacpe key. Is there
any other way than assigning each component and the form a KeyPress
event. While this works, is seems to me very clumsy way of doing it.

As JED wrote, a Cancel button is the most direct route. The button can
be "hidden" by making it 0 pixels wide if that is an issue. Another
alternative would be a "hidden" menu item if th form has a menu.
Good luck.

Alternatively he could set KeyPreview := True for the form, and put the
Escape key handling in the form-level keypress handler.
