??  How do you use M-V to rebind keys?

No, I would think that it's main purpose is to allow the user to
put actual control codes into the file.  Typing <M-V> <^C> seems
to put simply ^ and C into the file, but if you look at the actual
bytes with xxd, it is not 0x5e 0x43, but 0x03, the code for Ctrl-C.
And apart from control codes, to put characters into the file which
the user cannot type on the keyboard, the you look up the code
and type: <M-V>00cccc or <M-V>01cccc.

Indeed, the whole verbatim function is still missing from the docs,
even from the info document.  Work to do.

In nano it is not possible to rebind the actual <Home> and <End>
keys.  The ability was removed in revision 4797, because allowing
it amde other key combos stop working.  Nano's input routines are
not nicely divided in two layers, where first all kinds of keycodes and
escape sequences get translated to a simple enumeration of virtual
keycodes, and then these virtual keycodes can be bound to any function.
No, some codes get tied to function deep in the input routines.  This
can be fixed, but not quickly.
