Select All Keyboard Shortcut: Windows & Mac Guide
A comprehensive guide to the select all keyboard shortcut across Windows and macOS, with developer-friendly examples, accessibility considerations, and practical code samples to accelerate your workflow.
The select all keyboard shortcut highlights every character in the active field or document, letting you edit, copy, or format in a single action. On Windows and Linux, press Ctrl+A; on macOS, press Cmd+A. This universal shortcut works across most apps, from word processors and code editors to browsers and form fields.
What the select all keyboard shortcut does
The select all keyboard shortcut is a fundamental editing command that highlights every character in the currently focused element. This makes it possible to quickly replace, delete, copy, or format large blocks of content without dragging the cursor. According to Keyboard Gurus, the exact behavior can vary slightly between apps, depending on whether the target is a plain text field, a rich text editor, or a custom canvas. In simple text fields, the shortcut selects the visible content, while in editors with wrapped content, it may select the entire document or the current container.
To illustrate, here are a few concrete examples.
<!DOCTYPE html>
<html><body>
<textarea id="t" rows="4" cols="50">Sample text here...</textarea>
<script>
const ta = document.getElementById('t');
ta.focus();
ta.select(); // selects all text inside the textarea
</script>
</body></html>import tkinter as tk
root = tk.Tk()
text = tk.Text(root)
text.pack()
def select_all():
text.tag_add('sel','1.0','end')
text.focus()
select_all()
root.mainloop()[
{ "action": "Select all in editor", "command": "editor.action.selectAll" },
{ "action": "Select all in document", "command": "workspace.findAll" }
]Common variations:
- In web browsers, you can often rely on the OS shortcut irrespective of the input type.
- In code editors, the editor itself may expose a dedicated command named editor.action.selectAll.
- For accessible design, ensure focus is inside the target control before triggering the selection.

Steps
Estimated time: 25-40 minutes
- 1
Identify target area
Focus the element you want to select (text field, editor, document). Ensure the app is ready to receive keyboard input.
Tip: Click the field or use Tab to focus it before triggering the shortcut. - 2
Use platform shortcut
Press the platform-appropriate keys: Windows/Linux users Ctrl+A, macOS users Cmd+A. The content should highlight.
Tip: If nothing highlights, verify focus is inside the correct control. - 3
Verify selection
Check that all intended content is selected. If not, move the caret to the start and repeat with the shortcut.
Tip: Some editors only highlight a single container; use app-specific select-all if available. - 4
Perform post-selection actions
With content selected, you can copy, format, delete, or replace in one step.
Tip: If replacing, paste new content immediately after selection. - 5
Accessibility consideration
If users rely on screen readers, announce the action (e.g., “All text selected”) to convey state change.
Tip: Consider adding an explicit button for accessibility accommodations. - 6
Optional automation
For repetitive tasks, wire the shortcut into a script or macro to standardize behavior across apps.
Tip: Test across apps to avoid unexpected behavior.

Got Questions?
What is the select all keyboard shortcut?
The select all keyboard shortcut highlights every character in the currently focused element, enabling quick edits, copies, and formatting. It uses Ctrl+A on Windows/Linux and Cmd+A on macOS. Its exact behavior can vary by app, especially in rich text editors.
The select all shortcut highlights everything in what you're focused on, using Ctrl+A on Windows and Cmd+A on Mac.
Does it work in all apps?
Most apps honor the standard OS shortcut, but some specialized editors or custom canvases may define their own commands or limit selection to a visible container. Always verify focus and app behavior.
Most apps support it, but some specialized tools may behave differently.
Why doesn’t my Select All shortcut work sometimes?
If keyboard shortcuts fail, check focus, keyboard bindings, and potential conflicts with other shortcuts or accessibility tools. Try triggering the app’s built-in select-all command from the menu to diagnose.
If it isn’t working, make sure the app is focused and there aren’t conflicting shortcuts.
Can I customize the shortcut?
Yes. Many editors and OSs let you rebind shortcuts. Look for Keyboard Shortcuts, Keybindings, or Preferences to map to your preferred keys.
You can usually customize the shortcut in the app’s settings.
Does Select All include hidden characters or formatting?
In plain text fields, it selects all visible content. In rich text editors, formatting codes or hidden elements may vary; app behavior determines what counts as part of the selection.
In some editors, the selection may include formatting markers, depending on how the content is stored.
What to Remember
- Master platform shortcuts: Ctrl+A (Windows/Linux) and Cmd+A (macOS).
- Test across apps since behavior varies by editor and field type.
- Use code examples to programmatically select text when building tutorials.
- Always ensure focus is inside the target element before triggering selection.
