41 d.zoom allows the user to interactively adjust the settings of the cur‐
42 rent geographic region using a pointing device such as a mouse. Like
43 g.region, d.zoom re-defines the settings of the geographic region.
44 However, d.zoom allows the user to change the current region settings
45 interactively, by either outlining the new region perimeter with a
46 mouse, unzoom or pan the region. The graphics display is updated by the
47 module.
48
49 After the user types the command d.zoom a mouse-button menu will appear
50 directing the user.
51
52 Additionally the region settings can be modified by running g.region.
53
55 Although it is not necessary that the user display a map in the active
56 display frame before running d.zoom, it is helpful to do this for ref‐
57 erence. Using parameter -f integrate a pan function, -h facilitates
58 the use for handhelds.
