Create new Group Shortcut?

Hi, i'm trying to get used to Tabs Outliner.

It's a great product, and I'm hoping to get a handle on my tab "problem" soon using this cool utility.

But I have a question: I can't find / figure out a hotkey to create a new Group under the cursor? I looked a few times already, but couldn't find it... so I'm dragging them from the menu at the bottom... but it's kind of... a drag... :) ...

I wouldn't write if I hadn't figured out by accident that pressing "L" while hovering the tree somewhere creates a dividing line... then I thought... there *HAS* to be a shortcut for creating groups! :D

Unfortunately "G" doesn't seem to work? Or is it maybe another plugin I'm using which breaks the shortcut? Should G work?

Or am I using groups the wrong way anyways?

I figured I'd create a catchall / quick group for some browser windows collecting dust and start dragging windows + tabs in there to get a handle on them quickly. Isn't that how I should be able to use them?

Thanks in advance

Daniel
