How do I take a screenshot of part of the screen?

On macOS press Command Shift 4 then drag to select an area. On Windows press Windows Shift S to open the snipping toolbar and drag the region you want.

How do I reopen a tab I just closed?

Press Command Shift T on macOS or Ctrl Shift T on Windows in most browsers. You can press it repeatedly to reopen tabs in the order they were closed.

Is anything I search uploaded?

No. The whole reference and its search run in your browser, so nothing you type is ever sent anywhere.

How do I copy and paste with the keyboard?

Press Command C to copy and Command V to paste on macOS, or Ctrl C and Ctrl V on Windows. To paste without formatting, use Command Shift V on macOS or Ctrl Shift V on Windows.

How do I switch between open apps quickly?

Hold Command and press Tab on macOS, or hold Alt and press Tab on Windows. Keep the first key held and tap Tab repeatedly to cycle through open applications.

What is the Mac equivalent of Ctrl on Windows?

How do I find text on a page?

Press Command F on macOS or Ctrl F on Windows to open the find bar in documents and browsers, then type the text you are looking for.

Keyboard Shortcuts Reference

Keyboard shortcuts reference — macOS and Windows

This searchable reference lists the keyboard shortcuts you use every day, with the correct keys for both macOS and Windows side by side. It is for anyone who switches between the two systems or wants to work faster without reaching for the mouse.

How it works

Shortcuts are grouped into sections — editing essentials, navigation & windows, files & Finder/Explorer, browser tabs and screenshots. Pick your operating system at the top and every row shows the matching key combination for that platform. Type what you want to do, like “copy” or “screenshot”, and the search filters the whole list in real time.

Example

A few of the most-used shortcuts, mapped across both systems:

Action	macOS	Windows
Copy	⌘ C	Ctrl C
Paste	⌘ V	Ctrl V
Undo	⌘ Z	Ctrl Z
Reopen closed tab	⌘ ⇧ T	Ctrl Shift T
Screenshot a region	⌘ ⇧ 4	Win Shift S

Everything runs in your browser; nothing you search is uploaded.
