Do you really? I've been using as my primary editor for last 10 years or so, I rarely make use of the grammar. I sounds fancy and powerful in theory but I don't end up using it that often (even though I'm aware of it).
That said I'm probably only an intermediate user, because I haven't put in the time to really make things like markers and macros part of my editing habits.
Thats fine. The main thing is not to confuse technique with repertoire.. like a musical instrument, putting time in to mastering scales and finger technique will get you a lot of finesse in tackling musical pieces but it's the quality of your repertoire (in this context the algorithms/languages/higher problem solving knowledge) is what will be what gets you the money. Still a practising a few scales every now and then...
That SO reply is a classic for a reason. If you don’t use the “grammar” you could be having a nicer time with your editor. Especially when editing code, being able, for instance, to pull out the contents of a pair of brackets, with or without the brackets, instantly, is quite convenient.
