I use a Corsair M95 mouse. I've programmed the side buttons for copy and paste, select all, refresh, and the activitation of my drop-down Tilix terminal. There are also the default forward/back and dpi buttons. It's more for productivity as opposed to programming though, as I use Vim for programming and all the commands are already easily accessible from the keyboard. The browser controls and copy and paste buttons are great for cases when I have a hand on my mouse but the other is not on my keyboard. The downside of this is that I oftentimes tap the side of the mouse when using a different computer (and realizing that there's no button to press) thanks to muscle memory.
