111 ;;;; EDT Emulation Commands
114 ;;; Almost all of EDT's keypad mode commands have equivalent
115 ;;; counterparts in Emacs. Some behave the same way in Emacs as they
116 ;;; do in EDT, but most do not.
118 ;;; The following Emacs functions emulate, where practical, the exact
119 ;;; behavior of the corresponding EDT keypad mode commands. In a few
120 ;;; cases, the emulation is not exact, but it is close enough for most
123 ;;; In a very few cases, we chose to use the superior Emacs way of
124 ;;; handling things. For example, we do not emulate the EDT SUBS
125 ;;; command. Instead, we chose to use the superior Emacs
126 ;;; query-replace function.
132 ;;; Emacs uses the regexp assigned to page-delimiter to determine what
133 ;;; marks a page break. This is normally "^\f", which causes the
134 ;;; edt-page command to ignore form feeds not located at the beginning
135 ;;; of a line. To emulate the EDT PAGE command exactly,
136 ;;; page-delimiter is set to "\f" when EDT emulation is turned on, and
137 ;;; restored to its original value when EDT emulation is turned off.
138 ;;; But this can be overridden if the EDT definition is not desired by
141 ;;; (setq edt-keep-current-page-delimiter t)
