When I need to interpolate a String variable into a quoted string literal in the Eclipse java editor, I generally type "++" and eclipse usually inserts another " after the latter one, so I then have to go past it with arrow keys and then backspace to remove the duplicate, then go insert some spaces in between the "++" and type my variable name.
This seems like a lot of work. I have found Practically Macro, but I thought there might be something built in for this situation which is very common for me.
