- Bring Back that Tab You Accidentally Closed
If you close a tab by mistake, don’t worry, you can bring it back by simply pressing Ctrl + Shift + T and get back to what you were doing. You can press Cmd + Shift + T to bring back a closed tab if you’re on Mac.
- Emoji Keyboard
No matter the topic, there’s probably an emoji you can use to represent it. To access your emoji keyboard, press the Windows Key +. (period) or Windows + ; (semi-colon) on Windows, and Cmd + Control + Spacebar on MacOS. You can scroll through all the available emojis and categories (People, Nature, Food & Drink, Celebration, Activity, Travel & Places, and Objects & Symbols) or search the full list of emojis from the search box at the top of the window.
- Enable Night Mode on All Your Devices
Enabling night mode can come in handy if you usually work at night or like to read with the lights off. Whether you’re on Mac or Windows, you might want to try using F.lux. However, both operating systems have some built-in support for night mode.
- Minimize All Windows
If you have several windows open and you want it to all go away without having to press the minimize button for each window, press Windows key + D, and it will all go away in a single snap. Additionally, you can press Win + D once again to restore minimized windows. Although you can also use Windows + M to show the desktop, some applications such as RocketDock can ignore this command and will stay visible. That’s why we recommend using Windows + D.
In macOS, you can go directly to the desktop by pressing both Command + F3. Pressing this keystroke combination will immediately activate the Mission Control “Show Desktop” feature in macOS and push all windows on screen aside to reveal the desktop of the Mac.
