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
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.
