Hey guys here are some shortcuts that I use basically every day I use my macbook. Many of these are similar to PC shortcuts (Command is the same as control I believe) Here's a key:Cmd=Command; Alt=Option/Alt; Ctrl=Control; Shift=Shift
So here's the list: Useful Shortcuts
Cmd+Z=Undo/Redo
Cmd+X=Cut
Cmd+C=Copy
Cmd+V=Paste
Cmd+A=Select everthing
Cmd+Option+A=Deselect everything
Cmd+E=Eject
Cmd+I=Get info
Cmd+M=Minimize window
Cmd+S=save for many programs
Cmd+O=Open
Shift+Cmd+S=save as for many programs
Cmd+N= new project for many programs, new window for browsers/finder
Cmd+Shift+N= Create new folder
Cmd+W=close window(for program or window for browser)
Cmd+Option+W= Close all Windows
Cmd+Q=Quit Program
Cmd+F= Find (word or phrase in text)
Cmd+Tab(hold)=view active programs and scroll to open program
Left Arrow=Start media over in media players or go back frame in some editing software
Right Arrow=Next song(iTunes) and next frame in editing software
Cmd+Delete=Move to trash
Cmd+Shift+Delete=Empty trash
Delete/Backspace=Go back while in browser
Cmd+`=Go to next window (if you have multiple windows open in a browser)
Cmd+Shift+3=Take screenshot of everything
Cmd+Shift+4=Select region for screenshot
Cmd+Shift+4+Space=Take screenshot of window
Cmd+Shift+Q= Log out
Cmd+Shift+Option+Q= Log out immediately
Random/Cool Things
Cmd+Option+D=Hide Dock
Cmd+Option+Ctrl+8=Invert all colors
It's quite a large list and these aren't even half of all the shortcuts, but these are shortcuts that I use a lot. I'm probably missing a few but these are the most used ones I guess. I'll edit if I can think of any more.
