Like most in the software development world, I'm allergic to the mouse, but there are times when no keyboard shortcut is available. I'm willing to jump through a lot of hoops for my keyboard shortcuts. As an example, I'll show you how I configured OSX so that I can see my prior locations in a browser back button with a keyboard shortcut (in this case, Ctrl+Cmd+Z). Chromium open issue 328709 requests this functionality.
First off, you need a tool which can move your mouse programmatically. There are a few tools which will do that, but the two main ones I encountered were xdotool for the ancient Unix/Linux X Window System and cliclick for OSX. After fiddling with xdotool, I settled on cliclick.
Using OSX's Automator, you can do a lot of cool things.[1] I'm no expert with Automator and find it incredibly confusing, but I stumbled around into Utilities -> Run Shell Script and created a .workflow 'service' file saved at ~/Library/Services:
This will now show up at System Preferences->Keyboard->Shortcuts->Services, where I mapped it to Cmd+Ctrl+Z.
Whew. And yet that's not the end of the story, as cliclick did not do a right-click. So I installed BetterTouchTool (view homebrew cask, of course) and mapped the key which cliclick triggered to right-click. I hit Cmd+Ctrl+Z at least a few times per day (sometimes dozens) and it saves me about a couple seconds versus the alternative, so I feel it was worth the set up time.

I foolishly experimented bash's bind for binding a key to cliclick, but of course that wasn't available outside of the terminal. I also played around with Karabiner (KeyMapRemap4MacBook) ↩︎
