Type "UNDO" + ENTER to perform and UNDO .
YOU ONLY GET ONE ! USE IT WISELY .
I did NOT add CTRL+Z because I think we have already waiting far
too long for an update . And also , I don''t want to encourage the
use of UNDO by making it easy to use anyways .
The reason for just 1 undo is because any more than 1 undo would increase the
memory requirements for PHOSIMP . And I want it to remain a relatively
light-weight application !
