Command (⌘) as primary modifier. All Safari shortcuts use Command in place of Ctrl. This is consistent with macOS system shortcuts and other Mac browsers.
Smart Search Field. Safari combines the address bar and search field into one, the Smart Search Field. The keyboard shortcut to focus it is the same as the address bar shortcut in other browsers, but what you type determines whether Safari treats input as a URL or a search query.
Reader mode. Entering and exiting Reader mode has a dedicated shortcut when the feature is available for a page (indicated by the Reader button in the address bar). Within Reader mode, text size, background color, font, and text-to-speech controls are keyboard-accessible.
Tab Groups. Opening, closing, and navigating between Tab Groups, as well as adding tabs to a group, can be done from the keyboard. These shortcuts are particularly useful if you maintain multiple groups for different projects or contexts.
Sidebar. Safari's sidebar holds bookmarks, history, Tab Groups, and the Reading List. It can be toggled and navigated by keyboard.
History and bookmarks. Opening history, navigating it, and managing bookmarks all have dedicated shortcuts.
