How to ignore keybindings if i am using certain app?

[loss-and-quick]

I have problems using emacs because the keybindings are the same, then awesome responds to them too. How can this be fixed?

In the end, here's the solution:

local function toggle_keybindings(c)
  if c.class == "Emacs" then
    root.keys({})
  else
    root.keys(globalkeys)
  end
end
client.connect_signal("focus", toggle_keybindings)
client.connect_signal("unfocus", function(c)
	root.keys(globalkeys)			 
end)
