1) I absolutely hate keyboard 2) I have a simple three-point mouse 3) I often do tiling 4) as such, I use quite a bit of ssb's and web apps 5)..those have no toolbar and thus missing a go back a page button. Since I'm a lazy bum and the twenty inch distance to the alt+left is a nono, I made a desktop entry on my panel to do just that. Works for (most) chromium based ones and Firefox. Works for pretty much aanything that has alt+left assigned to go back a page or directory. So, in case someone is just as lazy....( requires xdotool )
