Ideally, they should all be in one edit, to not clutter up the edit history page.
In particular, try to avoid being a Serial Tweaker, as it makes said history really messy.

You can paste it over to a text program if you need more time, just check the history to make sure no one made any last minute edits while you were doing that. On the other hand, you're not going to get in trouble for serial edits unless you get really bad about it (or if people suspect you're intentionally clogging up the history to hide something). It happens to everyone, where you fix one thing and then notice another thing that needs to be fixed five seconds later. Be careful, but don't lose any sleep over it.

I've done that a few times when doing a mega-fix blitz of particularly broken pages I've ran across in the past. Helps to have a text editor open so you can note the changes while you're doing them, instead of relying on memory of something you did in the middle of a 15 minute edit session.

Just wondering what the convention is for when one has multiple edits that they want to make on a single trope or media page. For example, say I notice two spelling mistakes and one zero-context example that I want to fix. Should I change all three of these in a single edit, or in three separate edits, or in two edits by type? Thanks!
Also, feel free to tell me if this question is in the wrong place — obviously, I'm new to this :)
