Move Client to Monitor Left/Right

When using more than two monitors you may want to send the current client to a left/right monitor, instead of cycling through all of them.

This is easy to achieve - edit your rc.lua, find the clientkeys line: awful.key({ modkey,          }, "o",      awful.client.movetoscreen                        ),

and replace it with something like: awful.key({ modkey,          }, "o",      function(c) awful.client.movetoscreen(c,c.screen-1) end ), awful.key({ modkey,          }, "p",      function(c) awful.client.movetoscreen(c,c.screen+1) end ),

In this example Mod4+o moves active client to the left monitor (or rather the one with lower number assigned by RandR), and Mod4+p sends it to the right one.
