    Object and Function Dropdowns

    At the top of the Code Editor are two dropdown lists:

    +

    A WithEvents variable (Dim WithEvents acct As Account, also Private or Public, in a module, a form or a class module) is listed as an object; its events are the ones its class module declares with Event. Picking one of them creates the handler acct_EventName with the event's own parameters, so it matches what the class raises. Selecting the variable when it has no handler yet creates the handler for the class's first event, as a control's default event is created.

    The editor shows one procedure at a time. Each procedure has its own buffer, and switching between them is instantaneous. The (General) section contains module-level declarations and code.

    Text outside the procedure being shown is never lost: lines typed above or below the SUB move to (General), a second SUB typed into the buffer becomes a procedure of its own, and a procedure whose SUB line was deleted becomes (General) text. When you leave an event handler that was generated and never edited it is removed; empty SUBs and FUNCTIONs you wrote yourself are kept. After a save the editor shows exactly what was stored (blank lines around a procedure are normalized). A section too large for the editor opens read-only, with a message in the status bar.
