I want to open a file in Vim like in Eclipse using Ctrl + Shift + R, or via the Ctrl + N option of autofill. Invoke a
p*.dat
or something like that (like in old' dos)you could also :browse confirm e (for a graphical window)
but you should also probably specify what vim version you're using, and how that thing in emacs works. Maybe we could find you an exact vim alternative.
