A custom control is just a group of other controls put together to provide something, well, custom.
In many (if not most) cases it's helpful to set the group's selectGroupedControls property to false, so that the user can interact with it using the pointer tool without touching its interior controls, even if the global selectGroupedControls property may be true (the group property effectively overrides the global property).
Most custom controls benefit from using a behavior script, so you can use copied of the control anywhere and keep the code in one place for simpler maintenance and enhancement.
Depending on the nature of the control, it can be useful to take advantage of before and after message types in the behavior script, so the functionality the behavior provides can be reliably performed regardless whether the user traps the same message with a simple "on".
That's it. Not much to them, and that's the beauty of custom controls: they make great ad hoc solutions for a wide range of reusable components in an app because they can be built with all the development efficiencies LiveCode script provides.
