How can I export or extract pictures from an iPhoto library to files and folders?

Select "Photos" in the Library (left column), but don't select any single photo -- leave all unselected. Then choose File>Export. The number of "items" (photos and video clips) appears in the dialog in the lower left corner, so you know how many you are exporting. You can then specify the format (JPEG, TIFF, PNG, Original). You can then pick (or add) a folder for all the files. After doing this, you'll have all the files in one folder.

You can also Control-click the iPhoto Library file, which is actually a package, and choose Show Package Contents. Then click the Masters folder to open it, and you'll see folders organized by year; inside are more folders organized by date and album, and inside them are photos in JPG format and video clips.

As per Apple, the proper way to back up an iPhoto library is to copy the entire iPhoto Library package file to another hard drive. That's the only way to copy the photos and the database, which includes albums, keywords, and all other iPhoto metadata.

macbook - Word and Excel Short Cuts

In Word
= fn + right or left arrow keys only take me to the "home" or "end of the particular line I'm on.
= fn + up or down do the same as the MS "pg up" or "pg dn"
= fn + command + (arrow keys) take me to the very beginning or end of the document (Word or Excel).

In Excel
= command + right or left jumps to the next cell that has info in it (skips empty cells)
= command + up or down jumps to the beginning or end of adjacent cells with info in them.
= fn + right doesn't do anything
= fn + left takes me to the beginning of whatever row I'm in.
= fn + up and down are the same as pg up and pg dn. So is command + up or down arrow.
= fn + command + left arrow takes you to the beginning of the document (same as "Cntrl + Home")

Mac keyboard shortcuts

To use a keyboard shortcut, hold down one or more modifier keys while pressing the last key of the shortcut. For example, to use the shortcut Command-C (copy), hold down Command, press C, then release both keys. Mac menus and keyboards often use symbols for certain keys, including the modifier keys:

If you're using a keyboard made for Windows PCs, use the Alt key instead of Option, and the Windows logo key instead of Command. Some Mac keyboards and shortcuts use special keys in the top row, which include icons for volume, display brightness, and other functions. Press the icon key to perform that function, or combine it with the Fn key to use it as an F1, F2, F3, or other standard function key. 

To learn more shortcuts, check the menus of the app you're using. Every app can have its own shortcuts, and shortcuts that work in one app may not work in another.
