How to customize the buttons in program toolbars in Mac

Ever wish there were a Print button next to the Reply and Forward buttons in the Mac’s Mail app, or a pair of Zoom buttons on the top of every Safari browser window?
Well, here’s the thing: you can add, remove, and rearrange the buttons in the “toolbar” of several familiar Mac programs.
Not every Mac application has a toolbar of buttons that you can customize, but many of them do, including Safari, Mail, Firefox, and even garden-variety desktop folders.
For example, say you wanted to add a Print button to the Mail app’s toolbar. To do so, just…

• Open Mail, click View at the top of the screen, then select “Customize Toolbar.” When you do, a menu with more than two-dozen available buttons will slide into view.
• Find the Print button, then click and drag it into the Mail toolbar.
• When the Print button is right where you want it (nearby buttons will scoot out of the way), release the mouse button.
• All set? Click the Done button.

You can also follow the same steps to add Zoom buttons in Safari, a Label button to the folder toolbar, and more.
And while you’re at it, you can drag unwanted buttons out of the toolbar, add more space between buttons, or even add or remove a Search box (assuming Search is an available option).

Bonus tip

Want to hide a toolbar? Just click View, then Hide Toolbar, or use the OPTION + COMMAND + T keyboard shortcut.
