In various programs you can often activate a button using an alt+c key binding, if for example the button in question is Close. How is it possible to do this in gWidgets2? Take this example: 

w <- gwindow("Buttons")
g <- ggroup(cont=w, horizontal=FALSE)

## various buttons

## without icon
b2 <- gbutton("ouvrir", cont=g)

## with a handler
b4 <- gbutton("click me", cont=g, handler=function(h,...) {
    if(svalue(b2) == "open")
        svalue(b2) <- "ouvrir"
    else
        svalue(b2) <- "open"
})

How can I have the c underlined in click me, and the handler of the b4 button activated when the user activates alt+c?
