Oracle Forms Developer – Form Builder Reference, Volume 1

Key-Fn trigger
Description
A Key-Fn trigger fires when an operator presses the associated key.
You can attach Key-Fn triggers to 10 keys or key sequences that normally do not perform any Form
Builder operations. These keys are referred to as Key-F0 through Key-F9. Before you can attach key
triggers to these keys, you or the DBA must use Oracle Terminal to map the keys to the appropriate
functions.
Definition Level form, block, or item
Legal Commands
SELECT statements, restricted built-ins, unrestricted built-ins
Enter Query Mode yes
Usage Notes
• Use Key-Fn triggers to create additional function keys for custom functions.
• The key description shown in the default menu’s Help->Keys menu will always be for the formlevel
trigger defined for that key. If there are any lower-level triggers (e.g., block-level triggers) that
are also defined for the key, their descriptions will be shown when focus is in the lower level (e.g.,
the block) and [Show Keys] is pressed, but they will not be displayed in the default menu’s Help-
>Keys menu.
• Not all keys can be remapped on certain operating systems. For example, the Microsoft Windows
operating system always displays the Windows Help System when F1 is pressed, and attempts to
close the application window when Alt-F4 is pressed.
Key-Fn trigger restrictions
Form Builder ignores Key-Fn triggers in Edit mode.
