It's always great to see people improve their workflows in creative ways. At the same time, I find it strange how insensible browser defaults are for productivity (why do ctrl+F & ctrl+G do the same thing?). Developers tend to zoom around in their text editor at breakneck speeds, but slow to a comparative crawl in the browsers themselves. If I press F12 in Chrome or Firefox, I have no idea where focus even goes.

My primary annoyance is how ctrl+L (and alt+D) is the standard "focus urlbar" keyboard shortcut. It's definitely one of the most useful actions, but the shortcut requires a large motion or two hands. I rebound it to ctrl+Q for a while, but reverted as I just kept closing browser windows on other people's computers.

Ultimately, I recommend any person who uses a program often to explore ways of using it more effectively, not just for speed, but also to prevent RSI.
