I can't find a shortcut that's working on my MacBook Air. In Windows you can either click the rightmost part of the task bar to show the desktop or hit Windows+D to show the desktop. How do I do this in El Capitan?
The default shortcut for showing the Desktop is:
Technically, the official name is ⌘Cmd-Mission Control but unless you know what "Mission Control" is, you would end up searching for that as well.
Apple has a really good listing of all it's shortcuts - I keep this bookmarked for quick reference.
If you don't really like the Cmd+F3 option (the apps hovering at the corners don't really feel like "I've reached my desktop" for me) and need the exact same Windows-style Windows+D feature, you can try this,
- Create a new desktop
- For the most frequently used applications on your dock, right-click on them, and select Options->Desktop 2.
- Go to System Preferences->Keyboard->Shortcuts->Mission Control and assign shortcuts for your main desktop and desktop 2.
Lo and behold, you have a shortcut to reach your desktop. This system works really well for me and helps me multi-task very well. It also has the added advantage of not minimizing any windows. All windows are a desktop away.
I also set my Finder app to launch in my main desktop as I use it to browse and open files, which open in other desktops.
Of course, this won't work for new apps unless you set the option for them too explicitly. But I feel the purpose behind the question was to improve your everyday workflow, which would only involve frequently-used applications. And this option will definitely help. (For me, I explicitly made Preview, Terminal, Chrome, Sublime Text and some 4-5 other apps to launch on the second desktop).
