As of Wall Worm 3.224, many of the MacroScripts for Wall Worm functions have a default modifier function when you hold down the SHIFT key when executing the command. This means that if you have made a custom keyboard shortcut with the SHIFT key for those functions, the function will not actually run. Those functions, instead, will launch the documentation page for that function.

For the most part, functions that are getting these modifier keys are those that are found in the main Wall Worm menus in the Max menu bar. This means that you should not use the SHIFT key when assigning custom keyboard shortcuts for Wall Worm functions found in the menu bar.
