| <h1>Selection</h1> |
| <p>The act of selecting a block of text to replace or to surround |
| with an element is performed the same in Vex as in most word |
| processors: by moving the caret while holding the <b>Shift</b> key |
| or by dragging the mouse between two positions. The main difference |
| is that in some cases, Vex will expand the selection so that it |
| does not span only a portion of an element.</p> |
| <p>To see this in action, place the caret in the middle of an |
| inline element containing some text. While holding the <b>Shift</b> |
| key, move the caret towards the end of the element. As the caret |
| passes the end marker for the element, note that the starting point |
| of the selection jumps to the start of the element. If you move the |
| caret back inside the element (while still holding <b>Shift</b>), |
| you'll notice that the start of the selection jumps back to its |
| original place.</p> |
| <p>When a block element is selected, Vex draws an outline around |
| the entire block, showing the element name in the lower right |
| corner. This allows you to see that the entire element is selected |
| rather than just its contents.</p> |
| <p>This selection behaviour is Vex's way of preserving the |
| structure of the document. It is based on the assumption that |
| normally you want to manage entire elements.</p> |
