title: Vim: how to make the text I've just typed uppercase?
body: <p>Use case: I've just entered insert mode, and typed some text.  Now I want to make it uppercase.</p>
  
  <p>It can be done via <kbd>g</kbd><kbd>U</kbd><code>motion</code>.  However, I can't find the motion over the text entered in the recent input session.  It's somewhat strange and the concept of such motion is buggy (where to move if you've deleted text, for example?), but it may solve my problem.</p>
  
  <p>Or, are there other ways of making uppercase the text you've recently inputted?</p>
