Macbook Pro Short Cuts

I love using my Apple products because of all of the short cuts.  Don't you just love when you know something so well and enjoy how it makes your life easier?  I know I do and I want to know what short cuts you use often too!

Here are a list of the making-my-life-easier short cuts that I use daily:
Key:  Command=CMD  /  Option=OPT  /  Shift=SHFT  /  `=next to the number 1  / Control=CTL
What you do is press and hold the first key and (+) then press the second key and something happens.

Spotlight- CMD + Spacebar
This allows you to locate ANYTHING on your computer.  Now, when I say anything, I don't just mean an application or something on your desktop.  This is a quick search for anything written exactly as you write it.  When you "spotlight" something, on the top right of your Mac a magnifying glass turns blue and you can start typing.  I use this for opening applications, contact cards from Address book, my journal that I work on in pages.  The possibilities are endless..

Application Switching- CMD + Tab (don't let go of CMD but do let go of Tab after you press it)
You will see a list of all the open apps pop up on your screen.  If you look at your dock (the list of apps typically on the bottom of your screen) any app that has a blue dot under it is considered open and running, even if no window is open.
How I use this is to alternate between applications, going from Safari to Mail and then from Mail to iPhoto.  Every time you tap the Tab button while holding down Command you move apps.  Then when whatever app you end in, that app opens when you let go of Command.

Quick Look- highlight a file + spacebar
This is one of the hidden tricks that I love about my Mac.  Say you receive an email for a spreadsheet document for work.  You just need to take a quick glance at it now and really work on it later.  Single click the attachment (using Apple Mail, not in a web browser like Safari or Chrome), then just tap space bar once.  This will open a snapshot of that document.  This works when in finder, looking for that picture to upload to Facebook.  No need to know exactly where it is, just find a photo, press spacebar.
It is a quick look without opening the application needed to manipulate that file.  Great for PDFs in email and checking to make sure the file you want to edit is the right one.

I hope that you enjoyed these.  What are your favorite short cuts?
