NAME
    mev - a program to report mouse events

SYNOPSIS
    mev [ options ]

DESCRIPTION
    The `mev' program is part of the gpm package. The information below is
    extracted from the texinfo file,  which is the  preferred source of
    information.

    The `mev' program is modeled after `xev'. It prints to `stdout' the
    mouse console events it gets.

    `mev''s default behaviour is to get anything, but command line switches
    can be used to set the various fields in the `Gpm_Connect' structure,
    in order to customize the program's behaviour. I'm using `mev' to han-
    dle mouse events to Emacs.

    Command line switches for `mev' are the following:

    -C number
    Select a  virtual console to get events from. This is intended
    to be used for debugging.

    -d number
    Choose a default mask. By default the server gets any events not
    belonging  to the event mask. The mask can be provided either as
    a decimal number, or as a symbolic string.

    -e number
    Choose the event mask. By default any event is received. The
    mask can  be provided either as a decimal number, or as a sym-
    bolic string.

    -E   Enter emacs mode. In emacs mode events are reported as lisp
    forms rather than numbers. This is the format used by the t-
    mouse package within emacs.

    -f   Fit events inside the screen before reporting them. This options
    re-fits drag events, which are allowed to exit the screen bor-
    der,

    -i   Interactive. Accepts input from `stdin' to change connection
    parameters.

    -m number
    Choose the minimum modifier mask. Any event with fewer modifiers
    will not be reported to `mev'. It defaults to `0'.  The mask
    must be provided either as a decimal number, or as a symbolic
    string.

    -M number
    Choose the maximum modifier mask. Any event with more modifier
    than specified will not be reported to `mev'. It defaults to
    ` ~0', i.e. all events are received. The mask must be provided
    either as a decimal number, or as a symbolic string.

    -p   Requests to draw the pointer during drags. This option is used
    by emacs to avoid invoking `ioctl()' from lisp code.

    When the arguments are not decimal integers, they are considered  lists
    of alphanumeric  characters, separated  by a single non-alphanumeric
    character. I use the comma (`,'), but any will do.

    Allowed names for events are `move', `drag', `down' or `press', `up' or
    `release', `motion' (which is both `move' and `drag'), and `hard'.

    Allowed  names for modifiers are `shift', `leftAlt', `rightAlt',
    `anyAlt' (one or the other), `control'.

    When the `-i' switch is specified, `mev' looks at its standard input as
    command lines rather than events. The input lines are parsed, and the
    commands `push' and `pop' are recognized.

    The `push' command, then, accepts the options `-d', `-e', `-m' and
    `-M', with the same meaning described above. Unspecified options retain
    the previous value and the resulting masks are used to reopen the con-
    nection with the server. `pop' is used to pop the connection stack. If
    an empty stack is popped the program exits.

    Other commands recognized are `info', used to return the  stack depth;
    `quit' to prematurely terminate the program; and `snapshot' to get some
    configuration information from the server.

BUGS
    Beginning with release 1.16, mev no longer works under xterm. Please
    use the  rmev program (provided in the sample directory) to watch gpm
    events under xterm or rxvt. rmev also displays keyboard events besides
    mouse events.
