Create a link

You create a link from one button to another button so that the first button can use the action list assigned to the second button. Working with links has two advantages:

First of all using links saves memory. Instead of adding the same action list to several buttons, you just add the action list once and create links for other buttons.

Secondly it is much easier to update action lists when using links. Instead of modifying the action list for each button you assigned it to, you only modify the action list once and all the links to that button are modified too.
