Hotkeys don't work within editing window of a Google Doc

KeepTabs hotkeys don't work when the focus is within the editable part of a Google Docs page (they do if you click outside of it). The console reports this:

include.preload.js:341 Blocked script execution in 'about:blank' because the document's frame is sandboxed and the 'allow-scripts' permission is not set.

Not sure if we can actually fix this. Putting the key event handlers on window instead of document might work.

Yeah, looks like this can't be fixed due to the sandboxing. Moving the key event handlers to window (c975045) didn't work.

Turns out this was actually fixed by 1f92deb, so my initial conclusion was obviously wrong. Interestingly though, the UI does not show up when activating hotkeys within the editing window. I've opened #62 for this.
