Take a basic ‘copy’ command for example.
We all know (I hope!) the shortcut keys to copy something in any program. It’s two keystrokes and done in a single movement. The mouse equivalent has four separate movements: 1) Move the mouse to ‘Edit’, 2) Click ‘Edit’ 3) Move the mouse to ‘Copy’ and finally (after all that work!) click ‘Copy’.
It sounds pendantic I know, but any repetition of tasks that can be easily done through keystrokes is going to save us a lot of time vs using the mouse, especially when we consider how often we may use these commands throughout the day. This is one of the biggest advantages of Sublime Text over Dreamweaver… the program feels like it has been built around the developer and engineered to reduce keystrokes and mouse reliance.
