It is quite common to have multiple (read many) Subs in any given module. One thing that may help is the two icon buttons at the lower left of the code window.

The default button has FIVE lines (long, short, long, short, long). This displays all of the Subs in the module.

The other has THREE lines (long, short, long). This displays only the Sub the cursor is in.

It is a fast easy way to work on only the Sub you want to work on.
