Here’s an unsung hero of your keyboard: The Shift key. You already know it capitalizes letters, but it has a ton of other handy uses, too.

The Shift key actually reverses other common commands. Here are some examples:

• Ctrl+Z = undo; Shift+Ctrl+Z = redo
• Space = scroll down a webpage; Shift+space = scroll up on a webpage

• Ctrl+T = open a new tab; Shift+Ctrl+T = reopen the last closed tab
