st: Find Again and Copy in do-file editor

[<Stefan.Gawrich@hlpug.hessen.de>]

I agree that "mark&find" is a nice feature but as far as I know 
it's not documented (PDF-documentation GSW[13] paragraph "searching"). 
Different software uses this in different ways so the user never knows.

One can argue that - after the search box is closed - the search ends 
and F3 provides an additional search function based on the last inserted or marked string. 

But on the other hand F3 is named "Find Next" 
which makes it a logical successor of "Find".

In general it would be better not to have a search box but a search field 
in the top or bottom of the editor GUI (e.g. like in Firefox or Acrobat reader) 
which shows the active search string to the user and doesn't interfere with the text window.
