Why do you have to disable macros?

If you need to disable only the startup macros, keep the Shift key depressed
while the workbook is opening.

What is the best way to set breakpoints and step through code in Excel
VBA?
To edit the VBA code I have to tell Excel to disable macros when I open a
spreadsheet, and then I can't run the code to step through it.
