We have lots of wonderful keyboard shortcuts with which to compose an answer. One of these is CTRL-G, which brings up the image uploader.
Unfortunately, the resulting box requires me to remove my hands from the keyboard and click "Browse" before I get back to a browser file select tool which is keyboard friendly.
Attempting to tab to the "Browse" button moves the focus around in the greyed-out background, and you cannot type in the file input box. Even if you could, it points to C:\fakepath\
(due to this deferred bug), so typing the path there wouldn't work.
Please don't make me reach for my mouse.
