Items on the language table editor's options menu allow you to configure the LTE, adjust string extraction options, and re-extract strings.
LTE Options
The LTE options entry opens the LTE configuration window.
String Extraction Window - Non-Modal
Select this entry to open the SX window non-modally. When the SX window is open non-modally, you can jump back and forth between it and the LTE, useful for tweaking the exclusion rules while viewing their results in the language table. You cannot, however, command VBLM to reextract strings.
String Extraction Window - Modal
Select this entry to open the SX window modally, if you want to command VBLM to re-extract strings from within the LTE.
