Up at the top of the code window are two combo boxes.  For a form, you have
(General) and a list of objects that have events in the left combo box.
Click on Form.  In the combo box on the right, click on the event you want.
The focus and cursor will jump to that procedure in the code window.

For custom procedures in any code module (not just forms'), click on (General)
in the left combo box and click on the custom procedure listed in the right
combo box.  The focus and cursor will jump to that procedure.

Split the code window and you can have up to two procedures viewable in the
same module at the same time.  Tile the windows and you can have more than
one code module visible at the same time.
