Comment 1 for bug 493492

+1 for this. Maybe we could add something similar to "one hint at every access" which many programs have (non exactly that, because I find it extremely annoying).
It seems that even the GTG enthusiasts do not discover by themselves all the features of gtg.

EXAMPLE:
On #gtg irc, one user was saying:
  invernizzi: http://gtg.fritalk.com/public/Screenshots/0.2/gtg-0.2-all-shad.png
   how do you do hacking/gtg tags?
  @hacking/gtg ?
  to get the sub tag
