Comment 4 for bug 1020756

Here's an unbiased usability test I just did.

I asked my non-techy girlfriend to navigate the tree view (unpatched) using only the keyboard. She tried all the arrow keys then get frustrated, started trying: ctrl+right, shift+right, ctrl+down, shift+down, enter, alt+right, ctrl+shift+down, etc.

I stopped her then asked her to try my desktop (patched) and she got it right away.

When I told her it was the +/- keys, her words were "but it's so far away".
