Making a series of plots that proceed by a click

In the example below I would like to be able to control when I go to the next plot by a using mouse click (or keyboard entry)

for (i in 1:5){
    plot(1:i)
    Sys.sleep(1)
    #add something here that requests mouse click to proceed
}

Is this possible? There is a setting in the X11() help file caled 'clickToConfirm' but I can't work out what that does.

It would also be helpful to me to be to be able to scroll back and forth through plots using the arrow keys. Is this possible?

Currently if I need to look at lots of plots I output them into a big .pdf file and scroll though them all there, but that is a bit cumbersome.

Thanks

Tom
