Often you will want to copy, move, delete or fill large areas of your map. To accomplish this, you can use the appropriate commands from the Edit-menu.
Clear:
By activating the Clear-command, everything in the currently selected area
of the map will be deleted. Unlike for the Cut-command, the copy buffer
remains unchanged.
Cut:
By activating the Cut-command, everything in the currently selected area of
the map will be deleted and stored into the copy buffer.
Copy:
By activating the Copy-command, everything in the currently selected area is
stored into the copy buffer. The map itself remains unchanged.
(Note that multi-part objects will usually be copied only when their
"head"-tile is located within the selected area. Since the position of this
"head"-tile differs, expect some strange behavior there.)
Paste:
The paste command allows to dump the contents of the copy buffer onto the
map. First, select a square on the map to be the top-left corner of the
pasted area. Anything which doesn't fit within the borders of the map will
not get pasted. Multi-part objects which would reach outside of the map
borders, and be it only with their small toe, don't get pasted either.
Fill:
There are two fill commands: "Fill Below" and "Fill Above". The difference
between those two should be pretty obvious: If any selected map squares are
not empty, the new arches will get inserted either above top (-> Fill
Above), or below bottom (-> Fill below).
Both fill commands can be used in two different ways:
