I found this out when I was trying out Gunslingers in a private server,not too long ago.

If you put Float,Recoil Shot,and Float on a macro,in that order,it turns into a "Flash Jump".

The 1st Float is to get you into the air,it then goes straight into a Recoil shot.
Ok this is where it gets good;the next Float uses the sliding inertia made by the recoil shot to propel you into a faster lateral Float.I checked to see how it stacks up to other modes of transport,and it goes faster than a Red Draco,maybe even Teleport!

The distance it carries you depends if both skills are maxed,whether or not u have booster on,and whether or not u have high jump and speed.

Hope this helps any new Gunslingers~
