Command Line Editing
You can edit a line before it is sent to dcecp by typing certain control characters and escape sequences. To enter a control character, hold down the <Ctrl> key while pressing the appropriate character key. To enter an escape sequence, press the <Esc> key followed by one or more character keys. The escape sequences are case-sensitive; the control characters are not.
You can enter an editing command anywhere on a line. In addition, you can press the <Return> key anywhere on the line.
You can specify a number [n] as a repeat count. To enter a repeat count, press the <Esc> key, a number, and the command you want to execute.
For example, <ESC 4> <Ctrl-D> deletes the next four characters on a line.
Use the control characters and escape sequences shown in the following tables for line editing.

If you type rm /v and then press <Tab>, dcecp finishes as much of the name as possible by adding munix. If the name is not unique, the terminal presents a beep tone. If you enter <Esc ?>, dcecp displays the two possible complete file names: vmunix and vmunix.old. If you respond by entering a period (.) and by entering <Tab>, dcecp completes the file name for you.
