Might be a good idea since right now its behavior might not suit  
everyone's preference.

I am not sure I follow this. I tried this out and this is what the  
code looks like:

1) subroutine Initialize_Problem(Initial_Time, Nodal_Values) [hit enter]

2) subroutine Initialize_Problem(Initial_Time, Nodal_Values)
	real, intent(out) :: Initial_Time [hit enter]

3) subroutine Initialize_Problem(Initial_Time, Nodal_Values)
	real, intent(out) :: Initial_Time
	real, pointer       :: Nodal_Values(:)

In the end the code looks like this:

subroutine Initialize_Problem(Initial_Time, Nodal_Values)
	real, intent(out) :: Initial_Time
	real, pointer       :: Nodal_Values(:)
	[cursor will be here, indented to the right]

If this isn't how it is supposed to look like, could you describe how  
it is supposed to behave?
Would you prefer to have the line NOT indented after the enter (even  
if it sees the keyword "subroutine")? Or that it goes back to the  
leftmost margin if you enter a blank line by itself?

Right now the indentation is not context sensitive. Instead, it is  
based on keywords. In fact, if you enter "case" multiple times, it  
will look like this:

case(1)
	case(2)
		case(3)
			.....

Hopefully, tabs come out OK in this e-mail so I can illustrate my point.

Thanks for the feedback.
