DESCRIPTION

53       d.zoom allows the user to interactively adjust the settings of the cur‐
54       rent geographic region using a pointing device such as a  mouse.   Like
55       g.region,  d.zoom  re-defines  the  settings  of the geographic region.
56       However, d.zoom allows the user to change the current  region  settings
57       interactively,  by  either  outlining  the  new region perimeter with a
58       mouse, unzoom or pan the region. The graphics display is updated by the
59       module.
60
61       After the user types the command d.zoom a mouse-button menu will appear
62       directing the user.
63
64       Additionally the region settings can be modified by running g.region.
65

NOTES

67       Although it is not necessary that the user display a map in the  active
68       display  frame before running d.zoom, it is helpful to do this for ref‐
69       erence. Using parameter -f integrate a pan  function,  -h   facilitates
70       the use for handhelds.
