HC A Code Pattern is like one of those reciplies like sponge cake, it describes the underlying recipe which you can improvise on top of to create a strawberry sponge cake, a birthday cake like a clock, a fresh strawberry and cream sponge cake, a lemon passion fruit sponge cake. They are all fundamentally the same thing.
Code patterns are usually easy to reuse models that you can then customise, rather than a specific example for a specific purpose. They are all fundamentally the same thing. Much easier to remember a hundred code patterns than a thousand specific cases. FYI: As in my reply to Mohammad, I have built a button to toggle a field on any tiddler, to assist with my default toc above but now I am trying to generalize it so a new button can be created with little effort in future.
