I&m sure most Mac users know Command-C means copy and Command-V means paste, but there a host of other useful shortcuts that make a Mac user life much easier.
I&ve assembled this short collection to illustrate this truth:EscNever underestimate the power of the Esc key to get you out of trouble.
Say you're taking a screen shot and managed to select part of your screen for that shot, only to discover it's the wrong part & tap Esc and you won't need to worry about it.
That's basically the principle of Esc.
Use it to cancel a previous command.
Another example: Web page won't load and is sucking up your system resources?
