Useful Keyboard Shortcuts

Alright, I am not going to go over all of the keyboard shortcuts because there are so many of them and not worth remembering all of them, only the ones I think are useful. The Windows Keyboard shortcuts and Mac shortcuts are very similar but the main difference is instead of the control button, on a Mac, you would press the apple button or also known as the Command button.
(CTRL-or-Apple)+C: Copy
(CTRL-or-Apple)+X: Cut
(CTRL-or-Apple)+V: Paste
(CTRL-or-Apple)+Z: Undo
(CTRL-or-Apple)+B: Bold
(CTRL-or-Apple)+U: Underline
(CTRL-or-Apple)+I: Italic
(CTRL-or-Apple)+A: Selects Entire Document
(CTRL-or-Apple)+P: Print
(CTRL-or-Apple)+N: New Document or Tab
(CTRL-or-Apple)+O: Open Existing Document
(CTRL-or-Apple)+W: Close current Window
(CTRL-or-Apple)+Shift+N: Create New Folder

My Favorite is (CTRL-or-Apple)F: type a word and immediately finds that word on the page. Very useful and not many people know about it.

MAC Keyboard Shortcuts:
Control+Scroll: Zooms in on the screen
Apple+Shift+3: Take a picture of the screen will leave a .png file on desktop
Apple+Shift+4: Take a picture of the selection will leave a .png file on desktop
Also Hold Shift and Minimize Window

-you can also take a screen shot with Windows 7/Vista with the Snipping Tool
-everyone knows about Control+Alt+Delete
