Qed

From GTALUG

qed

qed is a text editor ("line editor") that has run on various platforms including Multics, CTSS, ITS, GCOS, Unix, and Linux.

Ritchie and Thompson characterize the CTSS version thus:

  QED is an interactive text editor available under GE-TSS on the GE 635. 
  QED has been characterized as hard to learn but easy to use. 
  In any event, it is much more powerful than most editors; 
  its text manipulation facilities approach those of SNOBOL.
