go over the ones in the file; in insert mode the new characters are put in
the file and the rest of the line is moved to the right.

Mistakes can be erased using <DELETE-CHARACTER>.

The switch /ICR (/NOICR) will cause (not cause) a new line to be inserted
in  the file when you type a carriage return.

The switch /BEEP will make the terminal beep once when entering insert
mode, twice when exiting, and not put the message on the bottom line.

The <MARK> command (^MK)

Marks the current cursor position. You can then move the cursor to any other
position, using any command which does not alter the file, and then type
<PICK> (or <DELETE-LINES>) to load the pick (delete) buffer.

The <MARK> command thus allows arbitrarily large cursor-movement picks and
closes.

The mark can be canceled by typing <ENTER><MARK>. This will re-display the
screen the way it was when you <MARK>ed it.

Related commands: <PICK>, <DELETE-LINES>, <PUT>
