Here is the AppleScript code that lists all the menu items pertaining to the Text Input menu on the Mac OS (the menu that shows up on the top right side of the screen when the Keyboard viewer is turned on in the system's preferences):

Or here's the same solution but much shorter and faster, come to think of it:

on expandEntireTree pWidgetID,pCardNumber,pStackName
lock screen
local pFoldArray,tK1s,tK2s,tK3s,tK4s,tK5s,tK6s,tK1,tK2,tK3,tK4,tK5,tK6,tL,pData
set the foldState of widget id pWidgetID of cd pCardNumber of stack ...

Here is one solution for expanding a tree completely, up to six levels. There may be a way to do it recursively but this solution has the advantage of avoiding a headache.

on unfoldEntireTree pWidgetID,pCardNumber,pStackName
lock screen
local pFoldArray,tK1s,tK2s,tK3s,tK4s,tK5s,tK6s,tK1,tK2,tK3 ...
