"Over the course of the next five days, I relied solely on my keyboard to navigate the web and my local hard drive. It was a limited form of digital detox, a way of trying to understand the way people used computers before the computer mouse became widely adopted for commercial machines in the 1980s. If I had to describe the experience of computing without a mouse in a word, I'd say it was ****ing fantastic. It took about a day and a half before I had memorized all the shortcuts that I would be using on a regular basis. All the other important shortcuts I wrote down on a notepad I kept on my desk for reference. I also had to do a little set up for certain applications, such as Gmail, which doesn't have many of its most useful shortcuts turned on by default, such as the ability to select all unread messages or the ability to move between messages with only a single keystroke.
By the end of my week without a mouse, many of the shortcuts were already beginning to feel like second nature. I found that they saved me a ton of time, especially on tedious tasks like deleting emails. Indeed, one shortcut evangelist suggests that switching to keyboard shortcuts in Gmail saved him as much as 60 hours per year. If nothing else, it made the experience of using a laptop way less miserable because I didn't have to touch the touchpad. [...] Admittedly, not everything was rosy without a mouse. I haunt a number of forums and found it a little tedious to have to ctrl+f whatever item I wanted to "click" on. Similarly, doing anything that involved image editing in Photoshop was basically impossible. I don't game on my PC, but from what I hear, this would also be quite difficult without a mouse."
