This is a very good question, I don't know, the manual doesn't mention
this printed representation, but it IMO should.  Please also M-x
report-emacs-bug.

BTW, I think it is very valuable for Emacs if people like you reading
the manual tell which errors and inconsistencies they find.  Most people
unfortunately don't dare to do so.


Thanks,

Michael.

The best help for improving writing is reading (and rereading).
Feedback from readers, from all backgrounds, is invaluable.

I wrote some notes [1] while I was reading the reader code in Emacs.
It may interests you.

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

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.

RE: About the `#^^' syntax

[Doug Lewan]

`#^' is used in the printed representation of a char table. (See the elisp info for "char-table type".)

I can't find `#^^', but it looks like it's for nested char tables from your example.
