Ian,
i've put your code on a php file wich i included on my template and add
name=KEYMAP on my input. like:
<input type="image" src="[ref]" name="KEYMAP" />
didn't work. what i'm missing?

Sorry, I didn't read your message properly.
To get the keymap to pan, you need some code in your web page.
My KEYMAP name is KEYMAP and the code to pan is something like this (PHP
code):
// Key Map
if ($_POST["KEYMAP_x"]) {
$dfKeyMapXMin = $map->reference->extent->minx;
$dfKeyMapYMin = $map->reference->extent->miny;
$dfKeyMapXMax = $map->reference->extent->maxx;
$dfKeyMapYMax = $map->reference->extent->maxy;
// Click Position
$nClickPixX = ($_POST[KEYMAP_x]);
$nClickPixY = ($_POST[KEYMAP_y]);
$dfWidthPix = doubleval($_POST[KEYMAPXSIZE]);
$dfHeightPix = doubleval($_POST[KEYMAPYSIZE]);
// Convert to a Geographic Co-Ordinate
$geoWidth = ($dfKeyMapXMax - $dfKeyMapXMin) / $dfWidthPix;
$geoHeight = ($dfKeyMapYMax - $dfKeyMapYMin) / $dfHeightPix;
$keymap_x = ($nClickPixX * $geoWidth) + $dfKeyMapXMin;
$keymap_y = $dfKeyMapYMax - ($nClickPixY * $geoHeight);
// Set Map Extents
$mapext_x = ($map->extent->maxx - $map->extent->minx) / 2;
$mapext_y = ($map->extent->maxy - $map->extent->miny) / 2;
//$my_extent = ms_newrectObj();
//$my_extent->setextent($keymap_x - $mapext_x,$keymap_y - $mapext_y,
$keymap_x + $mapext_x,$keymap_y + $mapext_y);
$map->setExtent($keymap_x - $mapext_x,$keymap_y - $mapext_y, $keymap_x +
$mapext_x,$keymap_y + $mapext_y);
$keymap_text = "<!-- KEYMAP CLICK=".$nClickPixX.", ".$nClickPixY."
GEO=".$keymap_x.", ".$keymap_y." -->";
}
There is a small bug in this code that I am still working on.
Hope this helps.
Cheers Ian
