MicroEMACS Quick Reference
=> MicroEMACS 3.8 Help screens (01/18/87)
M- means to use the <ESC> key prior to using another key
^A means to use the control key at the same time as the A key
^V or [Pg Dn] Scroll down M-< or <HOME> Beginning of file
^Z or [Pg Up] Scroll up M-> or <END> End of file
-----------------------------------------------------------------------------
=> (1) MOVING THE CURSOR
^F Forward character M-F Forward word Keypad arrows
^B Backward character M-B Backward word are active!
^A Front of line M-G Goto a line
^E End of line
^N Next line M-N Front of paragraph
^P Previous line M-P End of paragraph
-----------------------------------------------------------------------------
=> (2) DELETING & INSERTING
<-- Delete previous character
^D or <DELETE> Delete next character
^C or <INSERT> Insert a space
M-<-- Delete previous word
M-D Delete next word
^K Close (delete) to end of line
-----------------------------------------------------------------------------
=> (2a) MORE DELETING & INSERTING
<RETURN> Insert a newline <TAB> Advance to next tab stop
^J Insert a newline and indent M-^W Delete paragraph
^O Open (insert) line
^W Delete region between mark (set using M-<spacebar>) and cursor
M-W Copy region to kill buffer
^X ^O Delete blank lines around cursor
-----------------------------------------------------------------------------
=> (3) SEARCHING
^S Search forward from cursor position.
^R Reverse search from cursor position.
^X S Forward incremental search
^X R Reverse incremental search
<ALT> S Search for the next occurence of the last string (IBM-PC only)
<ALT> R Search for the last occurence of the last string (IBM-PC only)
-----------------------------------------------------------------------------
=> (4) REPLACING
M-R Replace all instances of first typed-in string with second
typed-in string. End each string with ESC.
M-^R Replace with query. Answer with:
^G cancel . exit to entry point
! replace the rest Y replace & continue
? Get a list of options N no replacement & continue
-----------------------------------------------------------------------------
=> (5) CAPITALIZING & TRANSPOSING
M-U UPPERCASE word
M-C Capitalize word ^T Transpose characters
M-L lowercase word
^X ^L lowercase region
^X ^U uppercase region
^Q Quote next entry, so that control codes may be entered into text
-----------------------------------------------------------------------------
=> (6) REGIONS & THE KILL BUFFER
M-<spacebar> set MARK at current position
^X ^X eXchange mark and cursor
A REGION will then be continuously-defined as the area between the mark and
the current cursor position. The KILL BUFFER is the text which has been
most recently saved or deleted.
-----------------------------------------------------------------------------
=> (7) COPYING AND MOVING
^W Delete (Wipe) region M-W copy region to KILL buffer
^Y Yankback save buffer at cursor
Generally, the procedure for copying or moving text is:
1) Mark a REGION using M-<spacebar> at beginning and cursor at end.
2) Delete it (with ^W) or copy it (with M-W) into the KILL buffer.
3) Move the cursor to the desired location and yank it back (with ^Y).
-----------------------------------------------------------------------------
=> (8) MODES OF OPERATION
^X M Add mode in buffer M-M Add global mode
^X ^M Delete mode in buffer M-^M Delete global mode
OVER Replaces (overwrites) rather than inserts characters
WRAP Turns on word wrap (automatic carraige return).
VIEW Allows viewing file without insertion and deletion.
CMODE Automatic indenting for C program entry
ASAVE Automatic saving of current buffer
EXACT/MAGIC Changes how search and replace commands work (see next page)
-----------------------------------------------------------------------------
=> (9) SEARCH AND REPLACE MODES
EXACT Upper/lower case is not ignored in searches
MAGIC Regular pattern matching characters are active
. Matches any one character
* Matches any any number of the preceding character
^ Beginning of line [ ] Character class enclosure
$ End of line \ Quote next character
-----------------------------------------------------------------------------
=> (10) ON-SCREEN FORMATTING
^X F Set fill column
Mn-<tab> Set tab spacing to n charecters between tabs stops
M-Q Format paragraph so that text lies between margins
^X = Position report -- displays line number, char count,
file size and character under cursor
M-^C Count words/lines/chars in marked region
-----------------------------------------------------------------------------
=> (11) MULTIPLE WINDOWS
Many WINDOWS may be active at once on the screen. All windows may show
different parts of the same buffer, or each may display a different one.
^X 2 Split the current window in two ^X O Change to next window
^X 0 delete current window ^X P Change to previous window
^X 1 delete all other windows M-^V Page down next window
M-^Z Page up other window
-----------------------------------------------------------------------------
=> (12) CONTROLLING WINDOWS AND THE SCREEN
^X ^ Enlarge current window M-<n> ^X W Resize window to <n> lines
^X ^Z Shrink current window M-<n> M-S Change screen to <n> lines
^X ^N Move window down M-<n> M-T Change screen to <n> columns
^X ^P Move window up
M-^L Reposition window
^L Refresh the screen
-----------------------------------------------------------------------------
=> (13) MULTIPLE BUFFERS
A BUFFER is a named area containing a document being edited. Many buffers
may be activated at once.
^X B Switch to another buffer. <CR> = use just-previous buffer
^X X Switch to next buffer in buffer list
M-^N Change name of current buffer
^X K Delete a non-displayed buffer.
^X ^B Display buffer directory in a window
-----------------------------------------------------------------------------
=> (14) READING FROM DISK
^X ^F Find file; read into a new buffer created from filename.
(This is the usual way to begin editing a new file.)
^X ^R Read file into current buffer, erasing its previous contents.
No new buffer will be created.
^X ^I Insert file into current buffer at cursor's location.
^X ^V Find a file to make current in VIEW mode
-----------------------------------------------------------------------------
=> (15) SAVING TO DISK
^X ^S Save current buffer to disk
or
M-^\ Save current buffer to disk
^X ^W Write current buffer to disk
^X N Change file name of current buffer
M-Z Write out all changed buffers and exit MicroEMACS
-----------------------------------------------------------------------------
=> (16) ACCESSING THE OPERATING SYSTEM
^X ! Send one command to the operating system and return
^X @@ Pipe DOS command results to buffer
^X # Filter buffer through DOS filter program
^X C Start a new command processor under MicroEMACS
^X D Suspend MicroEMACS into the background (UNIX BSD4.2 only)
^X ^C Exit MicroEMACS
-----------------------------------------------------------------------------
=> (17) KEY BINDINGS AND COMMANDS
M-K Bind a key to a command M-A Describe a class of commands
M-^K Unbind a key from a command
^X ? Describe command bound to a key
M-X Execute a named (and possibly unbound) command
{Describe-bindings}
Display a list of all commands and key bindings to a buffer
-----------------------------------------------------------------------------
=> (18) COMMAND EXECUTION
Commands can be specified as command lines in the form:
<optional repeat count> {command-name} <optional arguments>
{Execute-command-line} execute a typed in command line
{Execute-buffer} executes commands lines in a buffer
{Execute-file} executes command lines from a file
{clear-message-line} clears the message line during execution
M-~ clears the change flag for a buffer
-----------------------------------------------------------------------------
=> (19) MACRO EXECUTION
^X ( Start recording keyboard macro
^X ) Stop recording keyboard macro
^X E Execute keyboard macro
M-<n> {store-macro} Start recording named macro
!endm Stop recording named macro
{execute-macro-n} Execute macro n (where n is from 1 to 20)
-----------------------------------------------------------------------------
=> (20) SPECIAL KEYS
^G Cancel current command and return to top level of processing.
^U or Universal repeat. May be followed by an integer (default = 4)
M-<digit> and repeats the next command that many times.
