On a Chrome Code Reviews page, Google explains that 0.04 percent of page views are currently triggered by going back with the backspace button. In addition, 0.005 percent of page views are from people using the backspace key after a form interaction. "Years of user complaints have been enough that we think it's the right choice to change this given the degree of pain users feel by losing their data, and because every platform has another keyboard combination that navigates back." Inevitably, some users aren't happy with the change. Especially those that are careful or nimble-fingered enough to have never experienced such a backspace snafu.
One user responded in a Chromium bug tracker thread: "How is someone who grew up in terminal times expected to navigate back when using a two-button mouse? Are you suggesting that the only remaining options are Alt-Left (a two-hand key combo for that I have to move my mouse hand towards the keyboard, and then back) and the back button left of the omnibox (for which I may have to move the mouse across much of the whole display height/width, and then back)?"
Should there be a wide-scale backlash, it's possible Google will reconsider the tweak. In its Chrome Code Review, for instance, the company has anticipated how many will react: "We're doing this via a flag so that we can control this behavior should there be sufficient outcry." So what do you think? Good move, or a feature that shouldn't be removed from Chrome?
