Affecting Views from Smaller Focus Areas

Some aspects of these “smaller focus areas” - that is, areas that can hold keyboard focus aside from the major ones (pattern editor, disk browser, etc) - seem difficult to get at with scripting.

For example, say I’m trying to make a keyboard shortcut for the “More” button in the plugin effects list. There doesn’t seem to be a variable I can change to expand the list like there is with the disk browser. Is there a way?

What about expanding the external editor for LFO devices and instrument envelopes?
