Not always, but if you only do some of those incantations a few times per year, and what you remember is that you tended to get them wrong... it's a bit of a pain. This is partially why I switched to GUI clients for day to day. Tower (and maybe others) have an 'undo' which gives me a bit more confidence to try/test out things, because I know if it's wrong I can hit 'cmd-z' and be back where I was (at least until I push!).
