Depending upon the configuration of the version of X installed on your

particularly guilty of making bizarre keysym assignments to the keypad

V. HOW DOES THIS EDT EMULATION DIFFER FROM REAL EDT?:

perfect, but most EDT users who have tried the emulation agree that it is
quite good enough to make it easy for die-hard EDT users to move over to using

Here's a list of the most important differences between EDT and this GNU Emacs
