I try to keep a list somewhere, but I only pick one or two that are likely to be most useful and try to remember them until they're such a normal part of my workflow I don't have to think much about them anymore. Then I go back and pick a couple new ones to add.

The hard part is when you've reached the point where all your common use cases are covered and you're left with only uncommon cases. Then it's extra hard to remember you had a trick for dealing with the uncommon case.
