When I eval the (current-global-map) form:

(keymap #^[nil nil keymap 
#^^[3 0 set-mark-command move-beginning-of-line backward-char 
mode-specific-command-prefix delete-char move-end-of-line forward-char

clipboard-yank) (copy . clipboard-kill-ring-save) (cut . clipboard-kill-region) 
(f18 . clipboard-yank) ...)

There is a `#^^' syntax.  Maybe it is the printed representation for nested char tables, but it isn't mentioned in the GNU Emacs Lisp manual.

I don't think it needs to be. From src/lisp.h:

 A sub char table appears only in an element of a char-table, and
 there's no way to access it directly from Emacs Lisp program.

Can it be in the appendix of the manual?  For example, in the "Writing
Emacs Primitives" node, or another subnode of the "GNU Emacs Internals"
node.

Version: 24.3

I added a footnote, but the elisp manual is not intended to explain
absolutely every detail about Emacs. For some things you have to read
the code.
