Maybe I am doing it wrong... but either the way to perform autocomplete in the chat box has changed or it has a bug at the moment. I used to be able to press the up arrow to select a suggestion and press tab (I tried both tab and enter) and it would complete that part of the command in the chat window. In the same vein, I was able to start typing the @ name and then "up arrow and tab" to complete their name for quick and easy team invites. Now I have to click on the suggestion to get it to complete.

Is this a bug or has the functionality changed?
