After you have created your own tile set, and pasted it into Mombasa, the "Tile Key", that is, the names of the tiles, will be set to "Tile #1" through
"Tile #36". Choose the menu item "Edit Tile Key" from the tile menu to change the names. The dialog to change the names is pretty straightforward, just click on the arrows to move back and forth among the tiles, and type in the new names. Pressing return will automatically take you to the next tile.
