You must write the code as a Program unit then in the trigger reference the program unit.

e.g.

craete program unit clear_all
-------
PROCEDURE clear_all IS
BEGIN
CLEAR_FORM;
END;

REplace when_button_pressed with:
------
clear_all;

crate new trigger as:
------
clear_all;

No! There is no way to trigger a trigger except from causing the event - (allowing for custom event triggers - but they are weird! <technical term!>)

If you want the same code to fire from multiple triggers you need to either duplicate the code or reference a program unit (as suggested)
