Vim, reopen last closed window, that was in split

Question

Is it possible to reopen closed window in vim, that was in split?

Something like ctrl+shift+t with browser tabs?

Answer 1

No need for SHIFT:

nmap  :vs:b#

In conjunction with CTRL the characters are handled equally by vim, capitalized or not.

Actually also in the answer before, CTRLn and CTRLSHIFTN should both work.
