W3Z Map Editor Copy Terrain?

Just wondering is their a way to select terrain and copy it to another map? I can't seem to do it... I've never exatly used it other than to add more textures. I tried using the "selecte tilepoints" i made a square and tried to copy but it didn't seem to work...
:bangH:

Pick the Terrian Window and click on the

Image. Then hold down your left mouse and cover the whole terrian you want to cope (There should be some highlighting thing) Then press CTRL+C (After letting go of left mouse.) Hope that helps.

Or just go to terrain pallette, deselect all tile, cliff, height options, and press ctrl+a then ctrl+c. It's faster than clicking and highlighting the entire map anyway. But both ways work.
