The INSERT (abbreviated I) command inserts new text into a text
 buffer.

 Format: INSERT [range] ;line to be inserted
     Or: INSERT [range]
         text to be inserted
         ^Z

 The new text is inserted above the first line specified by range.  If
 you omit range, new text is inserted above the current line.

 If you choose the first form of the INSERT command, the text on the line
 following the semicolon is inserted and the editor does not enter insert
 mode.  This is the only form of the INSERT command that should be used
 in a startup command file or macro.

 If you choose the second form, EDT enters insert mode.  In insert mode,
 you can enter as many lines of text as you wish, terminating each line
 by pressing return.  Terminate insert mode by pressing CTRL/Z.

 The line following the last line inserted becomes the current line.
