Mac Tips

Special Keys

The Mac Command Key

You probably call this the "Apple Key", but it's officially called the Command Key and it is located near your spacebar. It is used on a Mac much like the control key is used on Microsoft Windows®; example: control-c on Windows copies and on a Mac we use command-c; control-v pastes on Windows and command-v pastes on Mac OS.

The Option Key

The Option Key is located near the Command Key and is sometimes called the ALT key. This key can frustrate a Windows user, as it doesn't work as a Windows ALT key does (you'll often use the Command Key on Mac where ALT is used in Windows), such as when tabbing through open applications: on Windows it's ALT-Tab, on a Mac it's Command-Tab.

The Control Key

The Control Key is located near the Command Key and has special funtions on a Mac (see "Right Clicking" below).

Exiting A Bad Program

On Windows, Alt+F4 will quickly terminate a program.

On Mac OS, Command+Q will quickly terminate a program.

The "3-Finger Salute"

On Windows, when a program stops behaving properly, you can press Control+Alt+Delete to invoke the Task Manager to make an application stop.

On Mac OS, you can accomplish the same thing by pressing Command+Option+Escape; this invokes the Force Quit menu and you can make applications stop.

"Right Clicking"

Sometimes you need to right click. On most computers it's easy, as they come with a two-button mouse. On Mac OS, you typically find a single-button mouse.

You can plug a two-button mouse in to a Mac and it will work. The reason is because two-button mice work on Unix and Mac OS is a Unix variant that uses parts from FreeBSD's and NetBSD's implementation of Unix.

You can also "right click" on a Mac with a single button mouse. To do so, you can do either of the following:

  1. Press and hold the Control Key while clicking.
  2. (This one only works if you have a Mac with a touchpad - usually a laptop) place two fingers on the touchpad while clicking.

Video Tutorial: Text Reveals Photo

I was showing off Kevin Crawford's 9 ways to reveal answers in a professional development session and demonstrated how to duplicate the effects Mr. Crawford achieved. Crawford's basis for that flipchart appears to have been inspired by Nine Instructional Strategies from Classroom Instruction That Works by Marzano R., Pickering D. and Pollock J. (arguably, it could have been other research). Revealing answers corresponds well with strategy 1 of the 9 strategies (Identifying Similarities And Differences specifically in Classifying). See also Marzano, Robert J.; Gaddy, Barbara B. and Dean, Ceri. What Works In Classroom Instruction. © 2000 McREL. Mid-continent Research for Education and Learning.

If you are referring to Crawford's flipchart, this was his way #7.

Crawford's Flipchart Tutorials

Who would use this, anyway?

Nearly every discipline has items that need to be identified. Here are some examples from the 5th-8th grade standards:


Describe and identify the five regular (Platonic) solids and their properties with respect to faces, shapes of faces, edges, and vertices.

Identify, define or describe geometric shapes given a visual representation or a written description of its properties.

Use visualization to describe or identify intersections, cross-sections, and various views of geometric figures.

Social Studies:

Identify significant examples of art, music, and literature from various periods in United States history.

Identify the similarities and differences within and among selected racial, ethnic, and religious groups in Tennessee.

Identify the founders of the world's major religions.

Identify ways resources are recycled.

Identify specific technological innovations and their uses.


Identify tools needed to investigate specific questions.

Identify the environmental conditions and interdependencies among organisms found in the major biomes.

Identify the function of the major plant and animal cellular organelles.

Identify the atomic number, atomic mass, number of protons, neutrons, and electrons in an atom of an element using the periodic table.


For this tutorial, you will need 4 pictures that are the same size and your trusty copy of ActivInspire.

To download a copy of these images, press the control key as you click and choose "Save Image As..." or perhaps "Download Image" (alternately if you have a little desktop showing, you can click the image and drag them to your desktop).

The Pictures

1. a hexagon
2. a square
3. a star
4. a triangle

The Video

In this short, 11:34 clip, I will go over:

  • Importing images
  • Changing the background color
  • Renaming images in the Object Browser
  • Demonstrating the use of Position in the Properties Browser
  • Finding the dimensions of your computer screen.
  • Finding the dimensions of an image.
  • Explain the concept of calculating the mathematical center of an image on your computer screen
  • Using the grid to align text on screen
  • The use of the Action Browser to invoke the Bring To Front Effect.

Here's a link to the video on schooltube - in case you can't see the video above.

Below I have attached "Revealer7.flipchart" so you can see the example in action. Just be sure to be using your Select Tool (arrow) and not your pen (else you'll draw on the picture...)

As a bonus, I attached the mathematical center flipchart in case you need to ponder on it for a while.
