Description

TCustomHotKey is an abstract class that encapsulates behavior of an object that is used to set a shortcut property at runtime. Accelerator key objects are used to perform an action quickly by enabling users to link the accelerator key to a combination of keystrokes that will execute the action. TCustomHotKey introduces properties to: 

Associate the accelerator key with keystrokes to perform an action 

Select a key combination at design time 

Invalidate specific modifier keys 

To change the key combination at runtime hold down the Alt, Ctrl or Shift keys or combinations of them and type a letter or number. The accelerator key property can then be assigned to the shortcut property of a menu item, for example. 

Hot key classes that descend from TCustomHotKey inherit the basic functionality of TCustomHotKey. Use TCustomHotKey as a base class for deriving specialized accelerator key objects.
