The CHANGES file tends to be the place to look for stuff like this. 
 From an entry for 2.5.0:

     o	There is support in both Rgui and Rterm for object/file name
	completion via the TAB key using package rcompgen.  This can
	be disabled by setting the environment variable
	R_COMPLETION=FALSE when starting R (e.g. in ~/.Renviron).
	(Words within quotes are interpreted as file names, others as
	R object names.  Use library(rcompgen); ?rc.options for more
	details, including tuning the behaviour.)

Subscribe to one of the feeds listed on 
http://developer.r-project.org/RSSfeeds.html if you want to hear about 
these things as they are developed (and watch typos being corrected, 
etc.), or just read through the "New features in this version: Windows 
specific" on the CRAN download site.

Some other help (on startup options) is available if you run Rgui 
--help, and more if you use the Help|Console menu item.  But there is no 
Rgui manual as such.  If you want to write one, I'd suggest putting it 
on the R Wiki, so you don't take on sole responsibility for maintaining 
it.
