You seem to be mixing things up a bit when it comes to getting the sheets rights for the color key effect.

Remember, everything needs to be on the SAME sheet, this means

• The color Key effect (Should be the first effect in the list for each sheet it appears on)
• The Magenta cutout-polygon (Which needs to be the topmost entity, clearly visible when sheet effects are off)
• The polygon you want to cut through.

The color key doesn't cut through any sheets below, it only cuts through entities on the very same sheet it is on. You can cut through multiple sheets, but that requires all of the three above for each and every sheet in the stack, it isn't enough to just add the effect to each sheet

For basic troubleshooting, just use the LIST command on both the magenta cutout-polygon AND the entity you wish to put a hole in. If they are not on the same sheet according to LIST, the setup isn't correct, and it won't work.

Also note that you cannot cut through things like symbols and inserted images.

I also noticed in your map that you have an entity with properties set up to be color 6 (magenta), but it is set up with a bitmap fill as well. Bitmap fills override solid colors, and thus makes it not work as a knock-out polygon. In addition to setting the color to magenta, you also need to make sure the fill style used for the polygon is Solid.

The MAP BORDER is a bit earlier so you can intentionally have things sticking out over it, like the mountains in one of the example maps. It is just part of the intention with the style.

No, you can't add hyperlinks in the gallery.

While not exactly the same, you can add all related maps to the same gallery album. When you click a map in a gallery album to view it, you can use the arrows in the top right corner of the viewer to go between all the maps in that album.

Unfortunately, there is no command to directly select entities on a given sheet. One workaround is to hide all other sheets (There is a checkbox for that in the sheets & effects dialog)

The ROT command will do that, it will allow you to rotate any kind of entity.

The Sequence of the command is basically

• ROT
• Select entities
• Pick center point for rotation. Can be clicked with a mouse, or enter coordinates at command line
• Set rotation angle. Can be selected by moving the mouse or type the angle in at the command line

One of the nice things with this command is that if you keep your mouse pointer far away from the object when rotating, it is easier to have control of the rotation because you must move your mouse farther to achieve the same amount of rotation as when it is closer, making it less sensible to accidental movements. You can also observe the angle in the top left of the status bar while you move your mouse, so you can move the mouse to get an idea of the value you want, and then just type in the desired value in the end instead of trying to click precisely.
