For a Quick Exit Remember to Use the Escape Key

In the top left corner of most PC and Mac keyboards is the humble and underused Escape key. It is labelled Esc on PC keyboards and esc on Mac keyboards.
On both PCs and Macs, pressing the Escape key usually cancels or aborts the current operation. To put it another way, the Escape key is the “get me outta here” option for many things. These include closing an open dialog box, getting rid of a button-less splash screen and closing a menu that you clicked on.
In most browsers, hitting the Escape key will stop a page from downloading. This is handy when a page has locked up or when it is downloading very slowly and you decide to go elsewhere.
Remember the Escape key next time you want to jump back a step.
