Subject: 27.1; doc-view-enlarge/shrink behaviour does not match documentation
Date: Fri, 26 Aug 2022 17:28:39 +0200
[Message part 1 (text/plain, inline)]
Hi,

I started Emacs with emacs -Q. Then, open any pdf file and try to use zoom
capabilities of DocView mode. Reading the DocView documentation I
understand that to doc-view-enlarge, first I should type C-c (as the
Prefix Command) followed by typing +. But this produces the message
C-c + is undefined
The way I got the zoom behaviour is typing + two consecutive times (++),
regardless of having typed before C-c or not. I am not sure if this is a
bug or Maybe I am not understanding the documentation in the correct
way.
Same happens for doc-view-shrink.
I keep below all the information produced by M-x report-emacs-bug.

Thank you!

Best regards,
Iago

Where do you read this?  In Emacs 27.1 in the Emacs manual, it says:

---
  You can enlarge or shrink the document with @kbd{+}
(@code{doc-view-enlarge}) and @kbd{-} (@code{doc-view-shrink}).
---

I read this in the DocView documentation as it appears when typing 'C-h 
m' in the DocView mode.

[Message part 1 (text/plain, inline)]
I've just found the quote inside the Emacs manual, but further, I 
realized now that in the DocView documentation I had seen, between the

C-c Prefix Command

line (above) and the

+ doc-view-enlarge

line (below) there is another Prefic Command line

ESC Prefix Command

so it was my fail typing C-c before +, which was the reason for no 
working. If I do ESC +, it works fine.


Sorry for the spam. Thanks!

Iago

In Emacs 27.1, this says:

key             binding
---             -------

C-c		Prefix Command
RET		image-next-line
C-n		doc-view-next-line-or-next-page
C-p		doc-view-previous-line-or-previous-page
C-r		doc-view-search-backward
C-s		doc-view-search
C-t		doc-view-show-tooltip
ESC		Prefix Command
SPC		doc-view-scroll-up-or-next-page
+		doc-view-enlarge
-		doc-view-shrink

This does not mean that `C-c' is the prefix key for all the stuff
that's underneath it -- it just means that `C-c' is a prefix command
(and is unrelated to the stuff below).

This display has been changed in Emacs 29 -- we don't mention the prefix
commands at all, because that brings no value.

No, the lines are unrelated to each other.

The enlargening command is simply `+' -- no more, no less.
