Ctrl-W in Hex View : Close window?

[meteorquake]

Ctrl-W closes other viewings, but in the hex view of a binary compare it offers to bookmark. This causes an issue when you are in a folder comparison rapidly viewing files with the left hand and want your right hand on Ctrl-W to close the comparison panes you throw up.

I think Ctrl-W should be consistent across the viewers?
