Günter, thanks for your reply.  I am using the Brief key-bindings.  For example, to mark 
an entire line for copy/cut, I use alt-l with the cursor anywhere in the line. 
Having a "clipboard app' running is new to me-- something new from the 
X-world:)  Most apps I use "just work" with cut and paste!
I also tried the menu options for rectangles, and again I do not get 
information to move from xjed to xjed.  One work around is to have the 
two files in two buffers of one invocation of xjed.  This does work.

However, I did discover a means of copy/paste between open xjed windows and with
some other apps:

1. Mark the text using alt-a, or alt-c to set the beginning point.

2. Then move the cursor with various keys to the ending point.

3. Press the middle mouse button and the highlighting disappears,
showing that something is being done. 

4. Mark the insertion point in the other xjed or app window and press the middle 
mouse button again.  

This is one of the X-window ways of doing things.  However, it does
not work when going from an xjed window to Kmail--I find that a number of other
apps do not work with Kmail either. It does work with the composer in Claws-mail,
another reason for me to switch mail apps.

In time, I will dechiper the abbreviations in the Key Bindings Help option. 
Even after 45 years using computers, there are always new things to learn:)
But then, I don't have that many years in which to learn them, so I have to 
be selective:)

Delbert
