Buffer page commands
--------------------
ESC N => Write current buffer to output file, clear buffer,
and read in next page from input file.

----------------------------
Search commands:
----------------
^S => Incremental forward search. Searches for string
as each character is input. Can only be exited with:
(1) ESC to signify stay at current location after
string found.
(2) ^G to abort and return to original location.
Notes: 1. "DELETE" removes characters from search
string.
2. When search string is null (empty) a 2nd
^S within a search operation uses the most
recent successful search string.
3. A 2nd ^S at any other time within a search
operation finds the next occurance of the
current search string.
^R => Incremental reverse search. Same as ^S except search
progresses backwards. Leaves pointer at beginning of
string found.
[Not yet implemented]
ESC X O => "Occurances". Display all lines containing a specified
string.
Instructions Summary (cont).
----------------------------
Kill and delete commands:
-------------------------
Kill operations either initialize the kill buffer with the removed
text, or append the removed text to the current kill buffer contents,
depending upon whether or not the pointer has moved since the last
kill operation. (appends if hasn't moved)
Delete operations remove the affected text and discard it.
^D => Delete next character.
^K => Kill to end of line / kill line terminator.
^W => Kill marked region.
^Y => Yank back last kill. (insert text stored in kill buffer)
ESC D => Delete next word.

victim.

ESC ^Y => Yanks (pulls) last defined TECO command into text
buffer.
ESC ^W => Append next kill to text already in kill buffer (if any).
(nullified by any pointer movement or text insertion)
^X ^O => Delete blank lines from current pointer to next non-blank
line.
[Not yet implemented]
^X # => Kill backwards to start of sentence.
[Not yet implemented]
"DELETE" => Delete character before pointer.
KEY

ESC Z => Return to TECO level. (can restart EMACS with MI$$)
ESC * => View last TECO command

not "hung".
^O => Open blank line for insertion.
^Q => Use next character as text. (inserts cmds as text)

80 characters per line or can be preceded with
an argument of form ESC<digits> which defines
number of characters in line.
[Not yet implemented]
ESC T => Exchange words before and after pointer (does
nothing if pointer is inside a word).
[Not yet implemented]
ESC % => "Query replace" --- Prompt for search string and its
replacement, then from current pointer to end of file,
find string and query user as follows:
(1) Space bar: go ahead and replace this occurance.
(2) ^G : abort query replace.
(3) Any other key: don't replace, find next.
^X I => Insert file at current pointer position. First executes
a ^X ^N to make room in the buffer.
[Not yet implemented]
ESC X C => Enter/exit "see-all" mode (shows ALL char in a file,
even non-printing ones, with special graphics)
ESC X D => Insert current date in text buffer in form MM-DD-YR

last defined EMACS macro. Pressing any key returns
to edit mode. Note some "commands" such as CRLF
are displayed in image mode. This is built into TECO.
^X T => "Toggle update" --- Forces screen update at current
command inside a macro. Useful for verifying macro
is executing properly by viewing results at specific
points, buts slows down execution considerably.
^X E => Execute most recently collected EMACS macro.
^X Q => When used inside a macro halts execution and waits for
the user to either:
(1) press space bar to continue with current macro.

----------------------------
Misc. notes:
------------
1. Most commands can be preceded with a repeat count of the form
ESC<digits>. Even "commands" which are self-insertions, I.E.
ESC20H inserts 20 "H"s in text buffer.
2. Commands which "view information" (such as ESC X O or ^X =)
wait for the user to press any key and then return the screen
to its normal window mode into the text buffer. The character
input by the single key stroke is discarded. The text buffer
is not affected by the view operation.
