  35 -- Example keybindings:
  36 --
  37 -- defbindings("WFrame", {
  38 --    kpress(META.."z", "zoom_client(_, _sub)")
  39 --    kpress(META.."z", "zoom_client(_, _sub, {swap=true})")
  40 --    kpress(META.."z", "zoom_client(_, _sub, {swap=false, goto=true})")

  43 -- zoom_client accepts a table that may contain the options 'swap'
  44 -- and 'goto'. Both are by default set to 'true'.
  45 --
  46 -- 'goto' controls whether to switch to the zoomframe
  47 --
  48 -- 'swap' controls whether to bring the zoomframe's active client
  49 --    into the current frame

  53 --
  54 -- zoom_client_set({zoomframename = 'foo'})
