To define a macro, press Ctrl-R and then type out the key strokes you want to be executed. Press Ctrl-R again when finished. You can then assign the macro to any key you like by pressing that key. The macro is executed when you press Ctrl-A and then the assigned key. The macro is also executed if you press Meta, Ctrl, or Esc and the assigned key, provided that the key is not used for any other function. Once defined, the macro commands go into the file .mc/cedit/cooledit.macros in your home directory. You can delete a macro by deleting the appropriate line in this file.
F1 hypertext help (it's primitive as hell, they do not reuse mc help format for some reason, but important to try)
F2 to save. Shift-F2 to save under a new name
F9 user menu (menu is not shown in default mode; important to try)
F10 to quit.
F11 user menu (important to try and to learn how to use)
The editor has top menu which is normally hidden but can be made visible by pressing F9 key. It provides interesting capabilities, including the ability to insert the content of the file under cursor.
CTRL + O -- Shows command line window/Restore editor
Ctrl-U -- undo
The internal file editor is a full-featured full screen editor. It can edit files up to 64 megabytes. It is possible to edit binary files. The internal file editor is invoked using F4 if the use_internal_edit option is set in the initialization file. The features it presently supports are: block copy, move, delete, cut, paste; key for key undo; pull-down menus; file insertion; macro commands; regular expression search and replace (and our own scanf-printf search and replace); shift-arrow text highlighting (if supported by the terminal); insert-overwrite toggle; word wrap; autoindent; tunable tab size; syntax highlighting for various file types; and an option to pipe text blocks through shell commands like indent and ispell. The editor is very easy to use and requires no tutoring. To see what keys do what, just consult the appropriate pull-down menu. Other keys are: Shift movement keys do text highlighting. Ctrl-Ins copies to the file cooledit.clip and Shift-Ins pastes from cooledit.clip. Shift-Del cuts to cooledit.clip, and Ctrl-Del deletes highlighted text. Mouse highlighting also works, and you can override the mouse as usual by holding down the shift key while dragging the mouse to let normal terminal mouse highlighting work. You can use scanf search and replace to search and replace a C format string. First take a look at the sscanf and sprintf man pages to see what a format string is and how it works. Consider following example. Suppose you want to replace all occurrences of an open bracket, three comma separated numbers, and a close bracket, with the word apples, the third number, the word oranges and then the second number. Then fill in the Replace dialog box as follows: Enter search string: (%d,%d,%d) Enter replacement string: apples %d oranges %d Enter replacement argument order: 3,2 The last line specifies that the third and then the second number are to be used in place of the first and sec- ond. It is advisable to use this feature with Prompt on replace on, because a match is thought to be found whenever the number of arguments found matches the number given, which is not always a real match. Scanf also treats whitespace as being elastic. Note that the scanf format %[ is very useful for scanning strings, and whitespace. The editor also displays non-us characters (160+). When editing binary files, you should set display bits to 7 bits in the options menu to keep the spacing clean.
Let the Midnight Commander type for you. Attempt to perform completion on the text before current position. MC attempts completion treating the text as variable (if the text begins with $), username (if the text begins with ~), hostname (if the text begins with @) or command (if you are on the command line in the position where you might type a command, possible completions then include shell reserved words and shell built-in commands as well) in turn. If none of these matches, file- name completion is attempted. Filename, username, variable and hostname completion works on all input lines, command completion is command line specific. If the completion is ambiguous (there are more different possibilities), MC beeps and the following action depends on the setting of the Complete: show all option in the Configuration dialog. If it is enabled, a list of all possibilities pops up next to the current position and you can select with the arrow keys and Enter the correct entry. You can also type the first letters in which the possibilities differ to move to a subset of all possibilities and complete as much as possible. If you press M-Tab again, only the subset will be shown in the listbox, otherwise the first item which matches all the previous characters will be highlighted. As soon as there is no ambiguity, dialog disappears, but you can hide it by canceling keys Esc, F10 and left and right arrow keys. If Complete: show all is disabled, the dialog pops up only if you press M-Tab for the second time, for the first time MC just beeps....
DEFAULT KEY DEFINITIONS
Keys may be redefined using an easy to use key learner. See the next
section on how to get this to work.
The following is a partial list of all default key bindings and their
actions, for reference. You will probably never need to refer to it
because most of the editor actions can be found in the menus. Note
that F14 is analogous to Shift-F4 etc. Also be aware that on some
machines, what X percieves as an Alt/Meta is actually some other
modifier key (our Sun-Sparc uses the diamond key).
Left left one char
Right right one char
Up up one line
Down down one line
Home beginning of line
End end of line

Ctrl-Down down one paragraph
Meta/Alt-Up scroll up one line
Meta/Alt-Down scroll down one line
Shift with any of the above keys will highlight at the same time.
Holding down the Control key while using the mouse to highlight text,
will cause the highlighted text to be displayed in inverse colour. You
will be able to select columns (arbitrary rectangles) of text and
drag and drop them as usual.
When editing an input line, Shift-Up or Shift-Down
will bring up a history of previous inputs.
