OK, I got it to work with a couple of fixes to the PickList entries.

{Snippet}select-prev-word{/Snippet}

(You had select-NEXT-word in your example)

{CopySelection}
{Right}
{AddGlossaryEntryDialog}
filename = ""
input = "text"
moveToTop = "n"
resumeUponOK = "n"
{/AddGlossaryEntryDialog}
{ResetTypingContext}

(There was an extra } at the end of the last line that added } after the short)

After I made these two corrections and moved Select Prev Words to be before Add Selected Words in PickList - it works great! Now I can keep hitting semicolon to select all the words, then hit SHIFT to open the current glossary window and add the selected words - just like I did before in IT7.

And I now recall that I had used a PickList in IT7 to create the same thing.

So, thank you very much! I'm also happy I was able to troubleshoot myself and get it working properly. Yay, me!
