What pressing the <ENTER> key prdouces is in fact a linefeed character. Therefore you can emulate it by sending such a character, which is represented by "^M" (CTRL-M).
If you are entering your program text via vi (or any other editor) you have to take measures though so that the editor doesn't enter an actual linefeed as would be the normal prceeding but will be treating the character as special character instead. In vi this is done by pressing "CTRL-V", which "escapes" the next entered character. After pressing CTRL-V in input mode you can press the ENTER key and you will see a "^M" appear (one character! you cannot separate the caret sign and the "M"). Manipulate this like any other text.
Analogously for "CTRL-D", but in this case you have an even easier means of producing it: "^D" is the EOF (end of file) character and the content of the /dev/null device is only a EOF character. The following command will put that character into the variable "eofvar" which you could manipulate like any other text:
Still, having said all that, zaxxon is most probably correct in pointing out expect to you. What you are likely willing to achieve is better done with it than with pure shell means.

When running MC in xterm or gnome-terminal, it doesn't seem to allow the use of Ctrl-enter and Ctr-shift-enter to copy marked files to the command line.
Does anyone know of another way to cause this to happen or a way to enable it under xterm/gnome-term?
With thanks,

evim
EVIM(1) General Commands Manual EVIM(1)NAME
evim - easy Vim, edit a file with Vim and setup for modeless editing
SYNOPSIS
evim [options] [file ..]
eview
DESCRIPTION
eVim starts Vim and sets options to make it behave like a modeless editor. This is still Vim but used as a point-and-click editor. This
feels a lot like using Notepad on MS-Windows. eVim will always run in the GUI, to enable the use of menus and toolbar.
Only to be used for people who really can't work with Vim in the normal way. Editing will be much less efficient.
eview is the same, but starts in read-only mode. It works just like evim -R.
See vim(1) for details about Vim, options, etc.
The 'insertmode' option is set to be able to type text directly.
Mappings are setup to make Copy and Paste work with the MS-Windows keys. CTRL-X cuts text, CTRL-C copies text and CTRL-V pastes text. Use
CTRL-Q to obtain the original meaning of CTRL-V.
OPTIONS
See vim(1).
FILES
/usr/share/vim/vim74/evim.vim
The script loaded to initialize eVim.
AKA
Also Known As "Vim for gumbies". When using evim you are expected to take a handkerchief, make a knot in each corner and wear it on your
head.

Most of Vim was made by Bram Moolenaar, with a lot of help from others. See the Help/Credits menu.
