Pro tip: Click and hold any icon in a top or bottom action bar in Android to see its label. Very useful with cryptic symbols. Not a solution, but eases the issue.
Doesn't work in Browser, the #1 androd app. Holding on the tab switch button or the three dots menu button does nothing. Holding Back opens the history menu, holding the app switcher does nothing, holding home runs the Google Now animation. Better luck in other apps maybe.
That's handy to know.
