To efficiently operate a computer, using only the keyboard.
This was a goal I pursued for the first few years in my early 20s, during my then-search for high levels of personal efficiency. During this earlier phase of my life, I often evaluated software based on whether they had hotkeys (i.e. keyboard shortcuts) available. Along the way, I learned some tricks for navigating the programs I used most often, including a local version of Microsoft Excel.
This post is to share some of the hotkeys I found helpful. As more come to mind, I will include them here :) feel free to bookmark this page if you find it helpful!
