I've been thinking more about using the keyboard like I do the guitar.
With the guitar, you usually rest your thumb on the back of the neck. It acts as a pivot as you play chords, melodies, and move across the strings.
With the keyboard, I'm finding my thumb act in a similar way. A lot of keyboard shortcuts I rely on use the Command key on my Macbook. That is pressed down by my left thumb and acts as the pivot by which I combine keystrokes with both hands. I am sure there are other pivot points like this — the Shift key comes to mind.
As I begin to think of the keyboard like a musical instrument, using my laptop becomes something like playing music, a miniature improvisation of keyboard shortcuts to navigate across windows and files and websites and programs like the notes that vibrate from the resonant strings of a guitar.
