That menu also lists any data objects which are present.

I suspect however that Sven is referring to 'code folding', which is
supported for some languages in Emacs.

Examples can be found here:

http://www.emacswiki.org/cgi-bin/wiki/FoldingMode

and here:

Besides the menu which Richard refers to, the Emacs Code Browser (ECB)
also supports functionality which is helpful.  I use it on Emacs 23 and
F7 and have put up a screen capture here:

You can see the following buffers in the image, which are configurable:

1. Upper left: Directory/File Selection Buffer

2. Middle left: Buffer History

3. Lower left: Object buffer with R function and data objects

4. Upper right: R code buffer

5. Lower right: Sweave .Rnw buffer


Note that I also use subversion and you can see the incorporation of
psvn.el in the modelines and the two upper left hand buffers with icons
indicating file svn status. I also have the tabbar loaded, which is
visible in the two right hand buffers at the top of each.

More information on ECB is here:

The CEDET tool package, which is required for ECB is here:

http://cedet.sourceforge.net/

and the psvn.el file is here:
