When in move tool double clicking a vector object takes you into node tool. It has been suggested that a double click on an object while in node tool should do the reverse and take you back into move tool (you could previously double click on the canvas / not over an object to return to move tool but this both loses your selection as well as not being possible if you are zoomed in). This has now been implemented in 2.4.
