In fact any Plugin installed can be called by Pressing key Tab then write it's name!

Or by making a ShortCut as usual!

There is nothing more in the UI if you have not installed some tricky UIs made by Users!
(what is not big easy! ;) Till Michael don't integrate some new tools for that! ;)

I can suggest you to make a little Text file where you write all your names' ShortCut well managed
so you have just to make a copy past after a Tab Key Pressing!
So that you avoid some headaches to install the tricky UIs! ;)
