- It's really about brain machine it interfaces. - Text is not "ideal" but it's much closer to being one with the computer if you know what you want done - Vs shortcuts - Shortcuts are great but even more specialized than commands. You need to do something all the time for it to be short it wotthy - Shortcuts are modal by app which means muscle memory can't really be developed - The exception here is cases where the same shortcut applies across multiple apps like command p - Commands are more memorable than shortcuts. All the km macros are a good example of this - Clicking is great when you don't know what you want. Great for browsing and exploring - Commands lend themself well to automation. - If you have a command you can paste it into a file too. If you have many commands pasted into a file you suddenly have a script - Commands are thus also a great intro to programming
