+Example (read only) files are
+in directory 
+.FR /n/kwee/t0/face/512x512x8 .
+.LP
+`Floating instruments' for editing
+can be dragged with button 2 to different locations.
+.LP
+.I Resolution.
+The tick mark on the long bar
+can be moved up or down with button 1.
+Printed
+to the right of the bar is the current resolution\(em
+a power of 2 representing the number
+of file pixels across the screen image.
+.LP
+.I Grid.
+Click button 1 at the circular button to toggle the grid.
+Turning on the grid is useful sometimes to see how
+fast a screen update is proceeding: it eats away the grid.
+.LP
+.I Write.
+Write the file on the host by clicking button 1 at the box labeled
+.LR write .
+The write box has a
+.L *
+if a change was made to
+the file since it was last written.
+.LP
+.I Runlength encoding.
+Clicking button 1 at this box toggles the mode of data transmission
+between host and terminal.

+.I Reopen.
+This instrument cancels any changes made to the file
+since the last time it was written.
+.LP
+.I Move/Pan.
+Click button 1 at one of the 5 areas of the diamond.
+The middle resets the display to a
+full size picture.
+Left, right, up, or down will move (pan) 1/4 screen in the
+corresponding direction
+(useful only on zoomed pictures).
+.LP
+.I Zoom/Unzoom.
+Click button 1 at
+.L Z
+(zoom) or
+.L U
+(unzoom).
+.L Z
+prompts with a square box to be positioned on the area
+of the picture to be inspected at full resolution.
+If you click button 1 before you confirm, the sides
+of the box are halved.
+Clicking button 2 doubles them.
+Any combination of two buttons cancels the zoom;
+button 3 confirms it.
+.LP
+.I Paint.
+Click button 1 at the box labeled
+.LR "+ = -" .
+Painting with
+.L +
+adds grey values to pixels;
+.L =
+assigns values;
+.L "-"
+subtracts values.
+Click button 1 at a pixel location to apply the paint.
+Click button 3 to sweep a rectangle to paint all pixels within it.
+Pick a paint value (default is white) by
+clicking button 2 at the grey scale at the bottom
+or at any pixel in the image.
+Click button 2 at the paint box to cancel the paint mode.
+.LP
+.I Smear.
+Pointing at a pixel with both buttons
+1 and 2 down averages it with its
+8 neighbors (most useful when zoomed in to pixel level).
+Typical usage: apply some white or black paint with the paint box,
+then smear it.
+.LP
+.I Probe.
+Click button 1 at the probe box
+.LR P: .
+Point at a pixel in the image.
+The
+.I x-y
+coordinates and the greyscale value of the pixel will be printed.

+grey scale bar to expand or compress the grey scale.
+.LP
+.I Rubber Sheet.
+The box named 
+.L sheet
+prompts for a rectangle.
+Sweep out the rectangle over an
+area you want to manipulate, then reposition the corners
+by dragging them to new locations with button 1.
+Confirm the selection with button 3.
+Other instruments
+are usable while the update proceeds.
