As you have probably heard at some point in your coding journey (thanks Marc), the faster you can make mistakes, the faster you can learn from those mistakes. To that end, I have been trying to use my mouse as little as possible lately and instead have been relying on keyboard shortcuts. It was a struggle at first to break from old habits, but the new muscle memory is finally starting to take hold. Here are some of the shortcuts that I have found most useful.

• Command-Tab (or Command-Shift-Tab): Toggle between apps.
• Control-Tab (or Control-Shift-Tab): Toggle between tabs in your browser.
• Option-Command-J: Open/close the DevTools (in Chrome).
• Control-Backtick (`): Jump into your console (while in DevTools or Visual Studion Code).
• Command–Left Bracket ([): Go to the previous page/folder.
• Command–Right Bracket (]): Go to the next page/folder.
• Control-Command-F: Full screen mode (or undo if already full screen).
• Command-X: Cut the selected item and copy it to the Clipboard.
• Command-C: Copy the selected item to the Clipboard.
• Command-V: Paste the contents of the Clipboard into the current document or app.
• Command-Z: Undo the previous command. You can then press Shift-Command-Z to Redo, reversing the undo command.
• Command-A: Select all.
• Command-R: Refresh the page.
• Command-F: Open a Find window.
• Control-T: Open a new tab.
• Command-W: Close the front window or tab.
• Command-H: Hide the front app.

And, of course...

• Control-Command-Q: Lock your screen. (Seriously, always lock the screen when you step away from your computer.)

These shortcuts make a good set to begin your practice. Learn them, love them, and in no time you'll forget that you paid a lot of money for a good mouse that you never use.
