When you write on a board, on a note, or mail someone, you enter message input mode. Everything you then type is added verbatim to a message buffer, and posted/sent when you exit the input mode with some termination char on the beginning of a fresh line. Additionally you can invoke editor commands which begin with a slash (/) and are followed by some control character. Available commands are as follows: Editor command formats: /<letter> /a - aborts editor /c - clears buffer /d# - deletes a line # (can also specify range) /e# <text> - changes the line at # with <text> /f - formats text /fi - indented formatting of text /h - list text editor commands /i# <text> - inserts <text> before line # /l [range] - lists buffer /n [range] - lists buffer with line numbers /r 'a' 'b' - replace 1st occurance of text <a> in buffer with text <b> /ra 'a' 'b'- replace all occurances of text <a> within buffer with text <b> usage: /r[a] 'pattern' 'replacement' /s - saves text Where <range> is optional and consists of "<low line> - <high line>" (space not being significant). You can leave off the <high line> part which means, "up to the end of message". This will then only execute the specified command on the given range of lines (low to high). Ending a message with '@' (aka the good old way (TM)) is equivalent to using the /s command in the editor.
