Left-clicking puts a cursor in the text. Try it. Clicking again in the same spot selects the surrounding word, and clicking yet again anywhere in the same word deselects the word and puts the cursor under the mouse. You can click and drag to select any contiguous portion of the text, and you can use keyboard combinations such as shift-cursor or control-cursor, or both: shift-control-cursor to extend or retract the current selection by words or lines, or to move around. Try them. It is not difficult to discover what these combinations do. You might even be familiar with them from text editors or word processors. Shift-clicking also extends the selection. It is much easier to understand how that works by trying it than by reading an explanation, so I won't give one.

Right-clicking in a window, indeed on any object, brings up a set of icons in a rectangle, as shown above, with a title at the bottom of the array. This array of icons is known as an object halo, or halo for short. Every graphical object in Squeak or Etoys has one. A single right click in a Workspace window brings up a halo with the title Workspace. A second right click shifts to a smaller halo with the title PluggableText. A third shifts to a larger halo labeled Text, with a different set of icons. We will explore the Halo below.
