The prefix 'C-x 5' is for frames, so 'C-x 5 5' creates a new frame.
The prefix 'C-x 4' is for windows, so 'C-x 4 4' creates a new window.
Also like 'C-x 1' keeps the selected window, 'C-x 4 1' shows the next
buffer in the same window while keeping it selected.

Recently Drew mentioned that there is the command 'tear-off-window'.
It would perfectly fit into the keybinding 'C-x 4 5' with mnemonics
that '4' (window) is detached to '5' (frame):
