⌘+L: This shortcut allows you to access Safari’s address line without using the mouse. You can then directly type the phrase you want to search for. This way, you can search or navigate to a different site without using the mouse. This shortcut works not only in Safari but also in Chrome browsers.
Safari has many nice shortcuts. For example, ⌘+T opens a new tab. ⌘+Z opens the last tab you closed. If you want to do this in Chrome or Opera, you should use the ⌘+Shift+T shortcut.
