Apple invented the shortcuts that you probably know, Microsoft ripped them and changed them, but very minor.
You might recognize something similar to, oh, say:
Command-Z: Undo
Command-C: Copy
Command-V: Pase
Command-A: Select All
Etc.., These things should pretty much come natural, they're the same.
Use Control+Eject to bring up the Power options. Shut Down, Restart, Sleep.
Command+Shift+Q will allow you to log out quickly.
Control+Shift+Eject will put your display to sleep, on notebooks.
Command+Option+Control+8 will invert the colors on your display. It seems soooo stupidly useless, but I've gotten a lot of mileage out of it.
Control+Zoom Up/Down will zoom into and out of your display.
Do trash an item such as a folder, you usually need to press Command+Delete. I don't know why this is. But once you've put an item in the Trash, press Command+
Shift+Delete to empty it.
Command+Space will open the Spotlight field. This means if I want to open a song file, it's as easy as pressing Command+Space and typing a part of the song or artist, then pressing enter.
Option+Command+Escape will bring up the option to force quit or restart applications. If somebody ever tells you to restart the Finder, the fastest way is to use this menu.
In Windows, pressing Enter will open a file or application. In MacOS, pressing Enter will make the file's name field editable. So to rename a file, select it, press Enter, type the name, press Enter. Done.
To open the application or folder, besides double-clicking, press Command+O.
All of the other shortcuts cane me located/modified in System Preferences>Keyboard to Keyboard Shortcuts.
They sure do make life so much easier
Also, the Force Quit menu is NOT equivalent to the Task Manager. The Task Manager is the Activity Monitor. Once you open the Activity Monitor, though, you'll never go back to that conglomerate crap on Windows again. It's a prime example of how MacOS is so much more clean and straightforward.
