     To eliminate parts of an image that are outside the region of interest
     defined by a rubber band, which can be larger than current window
     or screen size.

@b Interaction

     The following items are available from pop-up menu
@i     Doit
          crop with current region

@i     Done

@b  middlemouse & leftmouse
     Use left and middle mouse to drag the small crosses on the rubber
     band and thus both the size and location of the rubber band can
     be changed this way. If control key is down, dragging the mouse
     moves the rubber band rigidly.

@b  keyboard
@f   Escape
       Same as Cancel
@f   [1-9]
       set the step size for ijkl and xXyY commands.
@f   ijkl OR arrow keys
       Same meaning as in vi(1). The corner these keys apply to is
       the one closest to mouse. Shift key can be used to override
       this default behavior: if leftshift is down, ijkl moves the lower-left
       corner and if rightshift is down, ijkl moves top-right corner
       regardless which corner is last dragged by the mouse. 
@f   xXyY
       adjust the width/height of the rubber band

@b  Panning in crop
     Crop region larger than window/screen can be achieved by using
     the pan buttons in the edit panel.
       
@b  Reporting
     Current bounding area size and origin (lower-left corner) are
     reported in the file panel whenever changes to them occur. The step
     size for ijkl movement is also reported.

@b@C1 Warning
     Bit will perform framebuffer reads if there are text and sgfs present
     (rendered in Deferred mode).
