I realize that Vim's main author is Dutch, so I'll settle for those as well. I'm interested, do Vim's "control keys" have equivalents in the english language? You know, Ctrl-O for Open, Ctrl-N for New and so on.

Some of Vim's "control keys" could be assigned some meanings

(a) append / (i) insert (w) word / b (back one word)

These are just those that I thought off the top of my head.

Do they all have some meaning (:e ?)

I find it much easier to remember them if I know they mean something; they're not just randomly used keys.
