Do you use Google Chrome? More than half of the entire population on the internet now does. I work with software engineers, but remarkably few of them know all its secret shortcuts. So no wonder if the rest of us have missed some. Here are my favorite less-well-known-ones for the Mac:

• Press ⌘ and click a link. Opens the link in a new tab in the background.
• Press ⌘-Shift and click a link. Opens the link in a new tab and switches to the newly opened tab.
• ⌘-Shift-T Reopens the last tab you’ve closed.
• Press ⌘-Option and the right arrow together. Switches to the next tab.
• Press ⌘-Option and the left arrow together. Switches to the previous tab.
• Press Shift while clicking the + button in the top left corner of the window. Maximizes the window.
• ⌘-Option-H Hides all other windows.
• Type a URL, then press ⌘-Enter. Opens the URL in a new background tab.
• ⌘-L Highlights the URL.
• Select an entry in the address bar drop-down menu with your keyboard arrows, then press Shift-Fn-Delete. Deletes the entry from your browsing history, if possible.
• ⌘-Shift-D Saves all open tabs as bookmarks in a new folder.
• ⌘-Option-F Searches the web.
• ⌘-Option-C Copies the URL of the page you’re viewing to the clipboard.
• ⌘-Shift-Option-V Pastes content without source formatting (handy when writing a document in Google Docs or other WYSIWYG editor)

Here are the complete lists of Chrome keyboard shortcuts for Mac and Windows.
