I've started using snippets for code reviews, where I find myself making the same comments (for different colleagues) regularly. I have a keyboard shortcut opening a fuzzy search to find the entry in a single text file. That saves a lot of time.
As an aside, I find most of these commands very long. I tend to use very short aliases, ideally 2 characters. I'm assuming the author uses tab most of the time, if the prefixes don't overlap beyond 3 characters it's not that bad, and maybe the history is more readable.
