1.3 aaron 9: .Op Ar
1.2 deraadt 10: .Sh DESCRIPTION
11: .Nm
1.3 aaron 12: is intended to be a small, fast, and portable editor for
13: people who can't (or don't want to) run the real emacs for one
1.2 deraadt 14: reason or another, or are not familiar with the
15: .Xr vi 1
1.6 aaron 16: editor.
17: It is compatible with emacs because there shouldn't
1.2 deraadt 18: be any reason to learn more editor types than emacs or
19: .Xr vi 1 .
20: .Pp
1.6 aaron 21: Normal editing commands are very similar to Gnu Emacs.
22: In the following examples, ^X means control-X, and M-X means Meta-X,
1.4 deraadt 23: where the Meta key may be either a special key on your keyboard
24: or the ALT key; otherwise ESC followed by the key X works as well.

79: .Nm
80: differs primarily in not having special modes for tasks other than
81: straight editing, e.g., mail and news, and in not having special modes that
1.6 aaron 82: support various programming languages.
83: It does have text justification
84: and auto-fill mode.
85: Since it is written completely in C, there is no
86: language in which you can write extensions.
87: However, you can rebind keys and change some parameters.
88: There are no limits to line length or format.
89: Command, buffer, and file name completion and listing can
1.3 aaron 90: be done using the spacebar and
91: .Ql ? ,
92: respectively.
1.2 deraadt 93: .Pp
1.4 deraadt 94: Amonst other major differences, the
1.2 deraadt 95: .Nm
1.4 deraadt 96: configuration files are much simpler than real emacs.
1.7 ! aaron 97: There are two configuration files,
1.3 aaron 98: .Pa .mg ,
1.1 deraadt 99: and
1.3 aaron 100: .Pa .mg-TERM .
101: Here,
102: .Ev TERM
103: represents the name of you terminal type; e.g., if your terminal type
104: is set to
105: .Dq vt100 ,
1.2 deraadt 106: .Nm
1.1 deraadt 107: will use
1.3 aaron 108: .Pa .mg-vt100
1.6 aaron 109: as a startup file.
110: The terminal type startup file is used first.
1.1 deraadt 111: See the manual for a full list of the commands that can
1.4 deraadt 112: go in the files.
1.2 deraadt 113: .Pp
1.6 aaron 114: Here's another example sequence that you may find useful.
115: By default,
1.3 aaron 116: .Dq ()
117: and
118: .Dq []
119: are recognized as brackets, so bracket matching can be done.
120: The following defines
121: .Dq {}
122: as brackets, and turns on the mode that causes
1.1 deraadt 123: the cursor to "blink" to show you matching brackets.

138: .Sh BUGS
1.3 aaron 139: When you type
140: .Ql ?
141: to list possible file names, buffer names, etc.,
1.6 aaron 142: a help buffer is created for the possibilities.
143: In Gnu Emacs,
1.1 deraadt 144: this buffer goes away the next time you type a real command.
145: In
1.3 aaron 146: .Nm mg ,
1.4 deraadt 147: you must use "M-x 1" to get rid of it.
