marker |
                 marker=   plotting keyword

         selects the character used for occasional markers along a polyline,
         or for the polymarker if type is "none".  The special values
         '\1', '\2', '\3', '\4', and '\5' stand for point, plus, asterisk,
         circle, and cross, which are prettier than text characters on output
         to some devices.  The default marker is the next available capital
         letter, 'A', 'B', ..., 'Z'.

marks |
                 marks=   plotting keyword

         selects unadorned lines (marks=0), or lines with occasional markers
         (marks=1).  Ignored if type is "none" (indicating polymarkers instead
         of occasional markers).  The spacing and phase of the occasional
         markers can be altered using the mspace and mphase keywords; the
         character used to make the mark can be altered using the marker
         keyword.

mesh_loc |
                 mesh_loc(y0, x0)
              or mesh_loc(y0, x0, y, x)
              or mesh_loc(y0, x0, y, x, ireg)

         returns the zone index (=i+imax*(j-1)) of the zone of the mesh
         (X,Y) (with optional region number array IREG) containing the
         point (X0,Y0).  If (X0,Y0) lies outside the mesh, returns 0.
         Thus, eg- ireg(mesh_loc(x0, y0, y, x, ireg)) is the region number of
         the region containing (x0,y0).  If no mesh specified, uses default.
         X0 and Y0 may be arrays as long as they are conformable.
         For mesh_loc wrappers to duplicate the functionality of the
         digitize and interp functions in 2D, see the library file digit2.i.

mouse |
                 result= mouse(system, style, prompt)

         displays a PROMPT, then waits for a mouse button to be pressed,
         then released.  Returns array of eleven doubles:
           result= [x_pressed, y_pressed, x_released, y_released,
                    xndc_pressed, yndc_pressed, xndc_released, yndc_released,
    	        system, button, modifiers]
         If SYSTEM>=0, the first four coordinate values will be relative to
         that coordinate system.
         For SYSTEM<0, the first four coordinate values will be relative to
         the coordinate system under the mouse when the button was pressed.
         The second four coordinates are always normalized device coordinates,
         which start at (0,0) in the lower left corner of the 8.5x11 sheet of
         paper the picture will be printed on, with 0.0013 NDC unit being
         1/72.27 inch (1.0 point).  Look in the style sheet for the location
         of the viewport in NDC coordinates (see the style keyword).
         If STYLE is 0, there will be no visual cues that the mouse
         command has been called; this is intended for a simple click.
         If STYLE is 1, a rubber band box will be drawn; if STYLE is 2,
         a rubber band line will be drawn.  These disappear when the
         button is released.
         Clicking a second button before releasing the first cancels the
         mouse function, which will then return nil.
         Ordinary text input also cancels the mouse function, which again
         returns nil.
         The left button reverses forground for background (by XOR) in
         order to draw the rubber band (if any).  The middle and right
         buttons use other masks, in case the rubber band is not visible
         with the left button.
         long(result(9)) is the coordinate system in which the first four
         coordinates are to be interpreted.
         long(result(10)) is the button which was pressed, 1 for left, 2
         for middle, and 3 for right (4 and 5 are also possible).
         long(result(11)) is a mask representing the modifier keys which
         were pressed during the operation: 1 for shift, 2 for shift lock,
         4 for control, 8 for mod1 (alt or meta), 16 for mod2, 32 for mod3,
         64 for mod4, and 128 for mod5.

moush |
                 moush()
              or moush(y, x, ireg)

         returns the 1-origin zone index for the point clicked in
         for the default mesh, or for the mesh (X,Y) (region array IREG).

mspace |
                 mspace=   plotting keyword
              or mphase=   plotting keyword
              or msize=    plotting keyword
              or mcolor=   plotting keyword

         selects the spacing, phase, and size of occasional markers placed
         along polylines.  The msize also selects polymarker size if type
         is "none".  The spacing and phase are in NDC units (0.0013 NDC
         equals 1.0 point); the default mspace is 0.16, and the default
         mphase is 0.14, but mphase is automatically incremented for
         successive curves on a single plot.  The msize is in relative
         units, with the default msize of 1.0 representing 10 points.
         The mcolor keyword is the same as the color keyword, but controls
         the marker color instead of the line color.  Setting the color
         automatically sets the mcolor to the same value, so you only
         need to use mcolor if you want the markers for a curve to be a
         different color than the curve itself.
