command line

COMMAND LINE EDITING

You can edit the command line in MM, by using a set of control characters
similar to emacs.  In the following, ^A indicates control-A, and so on.

Move cursor:  ^B back 1 character            ^F forward 1 character
              ^A to beginning of line        ^E to end of line
Delete:   BACKSPACE character before cursor  ^H same as BACKSPACE
              ^D character at cursor         ^K from cursor to end of line
              ^W word at/before cursor       ^U entire line
Insert:       Characters are inserted wherever the cursor is
Transpose:    ^T transpose character at cursor with the one before it

Example: Suppose you want to see headers from melissa since Nov 19, 1990.
  Your fingers slip as you start to type and you stop midway:
       MM>g form mel
  As an example, to fix the two errors and continue you could do this:
  ^A to start of line, ^D to delete "g", type "h", ^F a few times to the
  "r", ^T to transpose "r" and "o", ^E to end of line, then type the rest:
       MM>h from mel since nov 19 1990
  Actually in this case it might be as easy to type ^U and retype completely.
  
The full set of control letters is as follows:

^A  Cursor to start of line		^N  Do next command in history
^B  Cursor back 1 character             ^O  [does nothing]
^C  Kill MM (not recommended)		^P  Do previous command in history
^D  Delete 1 character at cursor	^Q  Put output on screen [see ^S]
^E  Cursor to end of line		^R  Redisplay line
^F  Cursor forward 1 character		^S  Stop output to screen [see ^Q]
^G  [invalid command]			^T  Transpose 2 characters at cursor
^H  Backspace and delete		^U  Delete entire line
^I  Completion, same as TAB key		^V  Quote next character
^J  Newline, same as RETURN key		^W  Delete word at/before cursor
^K  Delete from cursor to end           ^X  [invalid command]
^L  Clear screen			^Y  Suspend MM
^M  Return, same as RETURN key		^Z  Suspend MM

For ^N, ^P, see "help command-history".  You can redisplay a command from
  history, and then edit parts of it, to avoid retyping the whole line.
