Here is a bundle of simple TextExpander actions -- create new snippet; create new snippet via clipboard or selection; toggle enable/disable expansion; open the TE dashboard; search snippets. All these actions do is use Applescripts to fire the hotkeys for these actions. Therefore, after installation: you MUST go into LB's action editor and edit the AppleScripts to conform to your custom hotkey combinations for TE. These actions ain't rocket science, but they make it convenient to access TE from LB. Cheers!
