No, currently B2T does not provide keyboard shortcuts. I considered it once in the past, but never got around to coding it. I may very well include them in the extension after I stop development for Firefox and bring all my extensions up to speed for Pale Moon. Right now I am just biding my time waiting for the axe to fall when Mozilla officially announces the deprecation of XUL and XPCOM. That way I will only have to be concerned with keeping compatibility with one platform (e.g., Pale Moon and any other Fx forks that are consistently compatible with it).
