  Editing Command Lines

  You can use keys to edit EVE command lines much like editing command lines
  as the system level. Generally, keys for text editing or for moving the
  cursor work the same way on the command line as in a text buffer. In
  effect, you edit one of two EVE system buffers---the COMMANDS buffer,
  which stores the commands you type, or the $PROMPTS$ buffer, which stores
  your responses to command prompts.

  Here is a summary of features for command-line editing:

     Canceling            To cancel a command, erase the command line and
                          press RETURN, or press a key defined as RESET
                          (such as GOLD-SELECT). Generally, if an EVE
                          command prompts you for additional information,
                          simply pressing RETURN at the prompt cancels the
                          operation (see help on Canceling). In some cases,
                          pressing RETURN indicates a default response.

     Cursor movement      To move the cursor on the command line, press keys
                          such as:

                             <-- ........ MOVE LEFT
                             --> ........ MOVE RIGHT
                             CTRL/H ..... START OF LINE
                             CTRL/E ..... END OF LINE

                          (The command line always uses a bound cursor.)

     Direction            Default direction of the COMMANDS buffer and
                          $PROMPTS$ buffer is REVERSE (to the left). To
                          change the direction, press a direction-setting
                          key, such as F11 (CHANGE DIRECTION). The new
                          direction stays in effect for the rest of the
                          session or until you change it again---it does not
                          revert to the previous direction when you
                          terminate the command or prompt. See help on
                          CHANGE DIRECTION.

     Erasing              To erase text on the command line, press text-
                          editing keys such as:

                             <X] ........ DELETE
                             CTRL/J ..... ERASE PREVIOUS WORD
                             CTRL/U ..... ERASE START OF LINE

                          In the COMMANDS buffer or $PROMPTS$ buffer, any
                          key defined as ERASE WORD (such as CTRL/J) works
                          like ERASE PREVIOUS WORD to emulate DCL command-
                          line editing.

     Mode for typing       Default mode of the COMMANDS and $PROMPTS$
                          buffers matches your terminal setting. To change
                          from insert mode to overstrike, or conversely,
                          press a key defined as CHANGE MODE, such as
                          CTRL/A. The new mode stays in effect for the rest
                          of the session or until you change it again---it
                          does not revert to the previous mode when you
                          terminate the command.

     Control codes        To enter control codes or non-printing characters
                          as part of a command or response, press a key
                          defined as QUOTE, such as CTRL/V. For example, to
                          enter an escape character, press CTRL/V and then
                          CTRL/[ (left bracket).

     Recalling            To recall a previous command or response to a
                          prompt, press CTRL/B or press the UP arrow---
                          effectively, scrolling back through the COMMANDS
                          buffer or $PROMPTS$ buffer. See help on RECALL.

     Other keys           You can also use keys you defined, including EDT
                          or WPS keys. Note that the EDT or WPS keypad
                          redefines CTRL/J as Delete Previous Word, which is
                          slightly different from the EVE definition, and
                          the EDT keypad redefines CTRL/U slightly
                          differently from EVE.

     CTRL/C               Pressing CTRL/C usually halts an operation.
                          However, if you are using keystroke journaling
                          (instead of buffer-change journaling), CTRL/C is
                          not recorded in the keystroke journal file. After
                          using CTRL/C, you should immediately exit, to save
                          your edits. Otherwise, if the system fails, you
                          may not be able to recover your work. This
                          restriction does not apply with buffer-change
                          journaling.
