Keep in mind how I setup my tray is how I do, nothing in this thread is concrete.
This thread will hopefully show how I set up my Tray for ease of use and hand strain and also introduce you to setting up a skilltray for static use toward using a Keyboard/mouse MACRO. Personally I find that fairly wasteful and unweildly, for one if you used your keyboard for skills, you will be all over the place.
I notice from a lot of screenshots and videos I see floating around the net that some ppl just use their BO tray and randomly have Capt/set skills distributed on the skill tray. This Thread does not use the Keybind File but Your Keyboard or mouse's Software/Profiles. Dark Has put together a Great STO KeyBind Thread located Here
