The seMatchingDefinitions Override Frontscript
How LiveCode Behaves Without the Plugin
When you right-click on a handler name in the LiveCode Script Editor, LiveCode looks through the stack containing the script's object to find a match. No frontscripts, backscripts or libraryStacks are searched which makes this feature much less useful.
For example, assume I am editing a script in one of my stacks and come across a function named BooleanToTrueFalse that resides in the script of a library stack.
