1) Go to any table, open "Data" tab
2) Go to "Filter" field
3) Press ctrl+space to call Autocomplete list
When the list is shown, I can navigate entries in it using up and down arrows, but I can't select an entry using neither tab nor enter nor space key. I have to mouse-click on the entry to use it. Sorry, but autocomplete that requires mouse to work is useless.
I think it was already broken in EA, but I wrote that off as something temporary broken due to being pre-release.
