<title>Selection</title>

<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>
