Tab/Enter in applicable places only works in some of them

[Dhwty]

At least one of these is Mac only. Others seem to apply in Linux, as well. Haven't tested in Windows.

Kurt: I'm trying to make a room. I typed in the room name. [Enter] won't automatically hit the submit button for me. Tab doesn't even go anywhere. So it's not either. Enter doesn't work on the set status page either. Nor can I tab through settings. Or press enter from the 'notify me on these words' textfield.
Dhwty: Tab/enter works on status. Hm, no, your enter problems seem to be a Mac thing. I can hit enter from the status field, and it submits.
Kurt: Oh! Wait a moment. Okay, enter does work from the status message box. But I can't tab into the your status box. It doesn't focus.
Dhwty: Checking this...
Kurt: I can't get the blue outline around it. If you select something from 'Your Status', it doesn't select.
Dhwty: Hmm. I can tab into it from the selection field.
Kurt: The typing bar stays the focus. I can't tab or shift tab into it.
Dhwty: Wow, yeah, can tab out of the select box, but can't tab into it.
Kurt: I can't SELECT the select box. Right, just for entertainment value. Select the away status. Click the status dropdown, and choose 'Away'.
Dhwty: No, apparently, I can tab into the select box, it just doesn't show me I've done it.
Kurt: Then, immediately press the up arrow.
Dhwty: nods Works fine. Selects Looking.
Kurt: Does not work here. No matter what I pick, the blue outline is on 'status message:'
