How to maximise a window horizontal or vertically?

Question

In awesome, what key binding can you use to maximise a window (in floating mode, of course) so that it maximise in just the horizontal or just the vertical direction?

I know that mod4 + m will maximise it fully in both directions so I kind of assume it will be possible to do a mapping to just one direction.

By default there is no such key binding. But you can create one. Use this snippet (or better add the key binding to your existing configuration) for your rc.lua file:

clientkeys = awful.util.table.join(
  awful.key({ modkey }, "F7",
    function(c) c.maximized_horizontal = not c.maximized_horizontal end),
  awful.key({ modkey }, "F8",
    function(c) c.maximized_vertical   = not c.maximized_vertical end),
)

It assigns horizontal and vertical maximization to mod-F7 and mod-F8, respectively.
