Backspace in Item Details

[dspeers]

Is there a way to modify the behavior of the backspace key when the focus is in the item details pane? In particular, when I'm typing text into a text field of a web browser window, I find that if I type the backspace key (like, I want to fix a typo), rather than backspacing over text it wants to navigate to the previous item detail page. It's very frustrating to have been typing a long bit of text and mistakenly hit backspace, only to find that all of the text is now lost as a result.
