How do I make a global change of category?

Question

I gave Quicken the wrong category for a regular monthly entry.  How do I make a global change so that Quicken changes the category to the correct one on all the previous entries, without me having to go in and change it, month by month?

There are several ways to do this, but I prefer Edit > Find/Replace as the most straightforward.
