Adding Tags?

I can't seem to figure out how to add tags or keywords to my clips in the new format. I have tried two different browsers on my mac (firefox and google chrome) and the words are deleted when I hit the return key. When I start typing some words I get a drop down menu with possible choices for the words, but often the word I'm trying to add is not in the list. For example if I want to ad "colorful", I might get "colorful lights". "colorful squares", "colorful background", colorful circles". etc, but not just "colorful". Sometimes when I click on a selection, it is added, other times it is just deleted. Am I missing something?

Just hit comma ,
after the desired word and it will register.

The old way from a couple years ago by using "xxxx" is gone, like he said a comma between words or phrases is how it works now. There is no spell check like other places so be careful.

There is a spell checker if you check the normal text area and are using Google Chrome. Google will underline in red any misspelled words automatically even if they were copied and pasted in the text box.

True, under the text and comma way it works. With the blocks it doesn't ... it could since it works with blocks at other agencies. Maybe a V2 upgrade.
