Jump to main line

In the Outline View of RSE, it is possible to jump to the start of any 
subroutine. Very useful. However, sometimes I want to jump to the start of 
the main line. I have not found a way to do this. I have to use the scroll 
bar to get to the point I want. Do I overlook something?

By the way: is there a way to find out if the source has changed (i.e. if 
lines have been inserted or deleted) since the last refresh? When the 
source has changed, the cursor is not positioned correctly. It would be 
nice if the user would be informed about the fact that the source was 
changed, and that a refresh should be done. (Maybe, it would even be 
better if a refresh was done automatically.)
