In this book, we showed you how to find and select blocks in the Blocks Editor. But, if you already know the block you want, there is a quick way to get it. All you have to do is click anywhere on the white space of the Viewer window and start typing. For example, if you want the When GuestsButton.Click event block, begin typing the word when and a drop-down list will appear, allowing you to choose the block you want among other blocks beginning with wh. Once you select the block, it will appear in the Viewer.

We didn't give you this shortcut initially because we wanted you to become familiar with where blocks were housed and how they were grouped (not because we wanted to make you work harder).
