Making maps for custom battles using the map editor

[Bombasticus Maximus]

Is there a well explained way to do this somewhere if so where as I want to make some. I have made one thats just adding:

custom_location Scottish Highlands 2
{
location 47 155
image data/menu/custom1.tga
sett_locked yes
summer no
}

But thats not making one that by yourself. :help:

Do you know how to get to and use the editor?

I have got the editor and have poked around some in it but I want to know all of the tricks.
