Subject: binding arrow keys in Tk


Anyone know how to bind arrow keys in Tk? The first bind call below does
what I want. The second doesn't have any apparent effect. My window has
some buttons as well as a canvas, and the buttons have focus, but I
don't bind arrows in the buttons (tried it, had no effect either).

# works
$root.bind "period" do
  $canvas.xview "scroll", 1, "units"
end

#doesn't work
$root.bind "rightarrow" do
  $canvas.xview "scroll", 1, "units"
end
