[R-gui] key-binding

["Unternährer Thomas, uth"]

Hi,
 
I studied the examples written by James Wettenhall and find the example "Pull-Down Menus and Popup Menus".
In this example James uses the following:
 
> copyText <- function() .Tcl(paste("event","generate",.Tcl.args(.Tk.ID(txt),"<<Copy>>")))

This calls a tcl-function an gives it the arguments .Tcl.args.
 
What I want is not to call a tcl-function, I want to call a R-function.
 
For those, who know emacs:
I want to set the key <F10> to call a eval-region function.
 
The Rcmdr-Packege by John Fox has exactly the feature I'm looking for. After pressing the button "submit", only the region the user selected would be evaluated. 
 
Can anybody give me a hint?
 
thanks a lot 
 
Thomas
