Learnt a neat trick from an old sysadmin colleague.
If you’ve written a command but realize you don’t want to run it right now but want to save it in your history you can just put a `#` in front of it (ctrl-a #) making it a comment and allowing you to save it in your history without running it.
When you’re ready to run it you find it and remove the preceding `#`
