About the `#^^' syntax

[Xue Fuqiao]

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 
keyboard-quit help-command indent-for-tab-command ...] #^^[1 0 #^^[2 0 
#^^[3 0 set-mark-command move-beginning-of-line backward-char 
mode-specific-command-prefix delete-char move-end-of-line forward-char 
keyboard-quit help-command indent-for-tab-command ...] self-insert-command 
self-insert-command self-insert-command self-insert-command self-insert-command 
self-insert-command self-insert-command self-insert-command self-insert-command 
...] self-insert-command self-insert-command self-insert-command 
self-insert-command self-insert-command self-insert-command self-insert-command 
self-insert-command self-insert-command ...] self-insert-command 
self-insert-command self-insert-command self-insert-command self-insert-command 
self-insert-command self-insert-command ...] (C-mouse-5 . mwheel-scroll) 
(S-mouse-5 . mwheel-scroll) (mouse-5 . mwheel-scroll) (C-mouse-4 . 
mwheel-scroll) (S-mouse-4 . mwheel-scroll) (mouse-4 . mwheel-scroll) (paste . 
clipboard-yank) (copy . clipboard-kill-ring-save) (cut . clipboard-kill-region) 
(f18 . clipboard-yank) ...)

There is a `#^^' syntax.  I don't know what it means.  I only know that the 
printed representation of a char-table is like a vector except that there is an 
extra `#^' at the beginning.  I have searched the Emacs manuals, but I don't 
find anything useful.  Can anybody help?  Thanks.
