...that I just didn't use this time: Compose the intended final result until it looks right in Preview, then cut-and-paste it to somewhere else (a temporary editor window that you never save will do), replace it with the "redirector" text, and then edit the target post much more quickly by just pasting in your saved intended-final-result.

But I only tend to do that when I go into the middle of a very active thread... And I can be arsed to.

Which I certainly can't for Norm.
