vim - What can follow "d" in normal mode? -

in answer this question, learned empty lines around cursor can deleted using key sequence dip in normal mode. astonished, looked vim help, vim says d may followed movement, i isn't (it brings insert mode normally).

1. what dip doing? i , p stand in context?
2. where can find documented? other "magic" characters can follow d?

you use vim you'd think, speak or write normal spoken language.

you have verbs d[elete], y[ank], p[ut], c[hange], v[isually select] , on.

you have sorts of objects w[ord], p[aragraph], t[ag] , on.

you have modifiers i[nner], a[round], t[ill] or /foo , many others , ability use {count} quantifier.

dip means "delete inner paragraph". vat means "[visually ]select current html tag", c2t; means "change here second next semicolon"…

like real language, learning full sentences won't far. basic vocabulary not large idea forget dip , learn d, i , p instead. learning dip, cib, gu/foo , millions of friends single commands takes more time , brain cells learning individual commands , simple grammar make work.

once know dcyv (verbs), ia (modifiers) , p (object), learning new object ) gives instantly di), da), ci), ca), vi), va) , on. each time learn new object or modifier (most single character), your vocabulary increases dramatically. isn't freaking cool?

also, :help d , :help ip have given answer.

as say, ":help motion.txt blow mind".
