Question Commenting out block of code in emacs in python mode
Hi,

I am not sure if this is the right forum to post an emacs question, but if you could point me to an appropriate emacs forum that would be useful too.

Anyway, here is the description of the problem:
I usually develop python code with emacs, emacs being in python code. On my desktop a version is installed and/or configured that way, so I easily can choose a region in the code and simply click on a menu option to comment out this block of code (i.e. at the begin of each line in the selected code two '##' are put). That is very convenient.
However, on my Laptop, running F12 and emacs 23.1.1, this menu option is missing! I searched within google and found the hint that by pressing 'C-c #' I also can comment out a selected region. But on my emacs it says: 'C-c # is undefined'. Am I missing something? Anyone any idea how to fix/install/update/solve this problem, so I can easily choose a couple of python lines and comment them out?


Thanks
Alex

mailcap.order

MAILCAP.ORDER(5)                                               Order Mailcap Entries                                              MAILCAP.ORDER(5)

NAME

       /etc/mailcap.order - the mailcap ordering specifications

DESCRIPTION

       The  order  of  entries in the /etc/mailcap file can be altered by editing the /etc/mailcap.order file.  Each line of that file specifies a
       package and an optional mime type.  Mailcap entries that match will be placed in the order of this file.  Entries that don't match will  be
       placed later.

   Example
           mime-support:*/*
           gv:application/postscript
           netscape:text/html
           less:text/*
           emacs:text/*

       The above would make any entries provided by the mime-support package (as found in the /usr/lib/mime/packages directory) take priority over
       everything else.  The gv package will be used over anything else when it comes to postscript documents.  Netscape will be used for any html
       documents  and  less will be used for any remaining text documents.  However, since neither netscape or less provide for editing documents,
       any edit or compose actions will fall through to the emacs rules.

       After modifying this file, be sure to run /usr/sbin/update-mime (as root) to propagate the changes into the /etc/mailcap file.

       Remember that this files takes package names and not executable names.  If you want to define rules that reference specific  programs,  the
       best way is to include them in ~/.mailcap or the user section of the /etc/mailcap file.

LIMITATIONS

       There  is  currently  no way to break out a certain type from a wildcard rule.  If, for example, both xv and gimp were to specify "image/*"
       rules, it isn't possible to use xv for gif images but use gimp for jpeg images.

       Also, I would like to add the ability to specify certain actions in the rules.  For example, if netscape were to have an edit  rule  but  I
       wanted to use emacs for editing/creating html documents, I could place a line like

         emacs:text/* action=edit|compose

       before  the  netscape  entry.  The update-mime program would then spit out entries such that netscape view rule comes before the emacs view
       rule but have the netscape edit rule comes after the emacs edit rule.
