Using Zhongwen to add to Skritter in a writeable doc

I know how to type “s” to add a word to my Skritter list when I’m using Zhongwen to read something on the web. However, it doesn’t seem to work if I’m in a writeable doc (like Google Docs); it just inserts “s” into the text. I read somewhere that I can do Alt-S, but that doesn’t work either. I think I did this successfully once before because there’s a single word in my Zhongwen list, but I can’t seem to do it again! Any help?

Thanks,
Karin

Not sure but you could try selecting, right click and search for the selection, then hover and press s in the results. Alternatively use A to add the word in any skitter window - I just press s with a random character to get one.
