[R-SIG-Mac] clear R console

[Marcin Jaworski]

Hi,

Is there a way to clear the R console using a shortcut like CTR-L uner Linux?
I started using MacOS X (Tiger), R 2.4.1 not so long ago. I found in R-help 
archive the following trick: 

p<-function(x) {
cat(rep("\n",30))
}

It's ok, but not especially convinient.
