When using a transparency mask, the effect is that the artwork underneath changes due to the black areas of the mask hiding the image and the white areas exposing the image. Here we have an colored background. I've placed a symbol that is black and white on the top.

Begin by selecting both images.

Locate the Transparency tab.

Click on the arrow and select Make Opacity Mask.

Now we can see the result.

Let's undo that last step and the click on the arrow again and uncheck New Opacity Masks Are Clipping.

We can now see the result that the mask has not clipped the entire piece. but only the upper artwork.

Now let's uncheck New Opacity Masks Are Inverted.

We can see that now the mask has been inverted.

We can edit the mask by Alt clicking on the thumbnail.

If we want to deactivate the mask, use Shift+click to do so.

Finally, if we want to reinstate the mask, we could choose Release Opacity Mask or Enable Opacity Mask.
