title: Android studio - how to show implementation in window ( like documentation)
body: <p>people. I have a question. Sometimes accidentally a window appears above some method with it's implementation. So I want to understand is there a shortcut for showing implementation of a method above the method(in new small window - like this when studio shows documentation) ? In my opinion it will be convenient to know it, because in that way it is not necessary to go to implementation and to go up and down in the code. Unfortunately I couldn't find it when I try to google it.
  Thanks in advance.</p>
