Answer 1

The way the shortcuts work is as follows :

Press Shift+Tab..Release both..Press 'i' or 'v'

--- Use Cases ---

1. Type a constant for e.g.

   Enter '1' 
   Press Shift+Tab then Press 'v'
   Provide a variable name
   

   

   Provide a variable name and you are done with.
   

   

2. Use a java internal class e.g. JFrame

   Enter 'new JFrame'
   

   

   Provide your choice
