Description
The OBJECT SET SHORTCUT command sets or dynamically modifies the keyboard shortcut associated with the object(s) designated by the object and * parameters for the current process.
If you pass the optional * parameter, this indicates that the object parameter is an object name (a string). If you do not pass this parameter, this indicates that the object is a variable or a field. In this case, you pass a reference instead of a name.
In the key parameter, pass a string indicating the key to associate with the object. You can either pass:
- a standard key name, for example "B"
- or a constant (or its value) from the Shortcut and Associated Keys theme:

In the modifiers parameter, you can pass one or more modifier keys to associate with the shortcut. To set the modifiers parameter, pass one or more of the following "Mask" type constants found in the Events (Modifiers) theme:
| Constant | Type | Value | Comment |
|---|---|---|---|
| Command key mask | Longint | 256 | Ctrl key under Windows, Command key under OS X |
| Control key mask | Longint | 4096 | Ctrl key under OS X, or right click under Windows and OS X |
| Option key mask | Longint | 2048 | Alt key (also called Option under OS X) |
| Shift key mask | Longint | 512 | Windows and OS X |
Note: When you omit the modifiers parameter, the object is enabled as soon as you press the key that was set. For example, if you associate the "H" key with a button, this button is enabled whenever you press the H key. This kind of functioning is to be reserved for specific interfaces.
Example
You want to associate a different shortcut depending on the current language of the application. In the On Load form event, you can write:
Case of
vLang="FR"
OBJECT SET SHORTCUT(*;"SortButton";"T";Command key mask+Shift key mask) // Ctrl+Shift+T in French
vLang="US"
OBJECT SET SHORTCUT(*;"SortButton";"O";Command key mask+Shift key mask) // Ctrl+Shift+O in English
End case
