Thank you so much for the quick reply to this question. I came across this situation while brailling marginal labels. So a 2 letter key followed by a space and then the text enclosed within braille grouping indicators is what is actually in the braille volume I am transcribing.

The marginal labels appear in an example student essay. I included information I believed would be enough to get the question answered. It seems I did not fully think it out as I should of provided the exact example and all that it entails. I have attached a similar example that has both an alphabetic wordsign and a shortform word that is not standing alone due to the braille grouping indicators. I have omitted text, represented by an ellipsis, for space considerations.  Thanks.
