Another (IDEA like) fast import (it does not require shortcut
knowledge) is showing small popup proposing solution that disappears on:
  - accepting it (hitting displayed shortcut Alt-Enter),
  - ESCaping it,
  - leaving wrong line or
  - typing on given line.

The same is used for create method, surround with try/catch,
add catch block or add exception to signature, ... except
that auto popup step shows small icon instead of full suggestion.
It expands to full suggestion list on (hidden/tooltip over icon)
shortcut Alt-Enter.

In other words fix action can be made more usefull even for
power users if tightly integrated with editor. 

It's questionable how can suggestion framework fit in. I can
imagine that more straitforward implementation goes directly
into java editor implementation. On the other hand it's 
'current line suggestion view' (that must be very, very fast).
