on the page belongs to a layer. There is no relationship between
32
32
layers and the <a href="manual_4.html">back-to-front ordering</a> of
33
33
objects, so the layer is really just an attribute of the object.
34
<p>Layers have several attributes. They may be editable or locked.
35
Objects can be selected and modified only if their layer is editable.
36
A layer may be visible or invisible. A layer may have snapping on or
37
off--objects will behave magnetically only if their layer has

<p>When editing a page in Ipe, there is one <em>active layer</em>. New
40
objects are always created in the active layer.
34
<p>The layers of the current page are displayed in the layer list, at the
35
bottom left of the Ipe window. The checkmark to the left of the layer
36
name determines whether the layer is visible. The layer marked with a
37
yellow background is the <em>active</em> layer. New
38
objects are always created in the active layer. You can change the
39
active layer by left-clicking on the layer name.
40
<p>By right-clicking on a layer name, you open the layer context menu
41
that allows you to change layer attributes, to rename layers, to
42
delete empty layers, and to change the ordering of layers in the layer
43
list (this ordering has no other significance).
44
<p>A layer may be editable or locked. Objects can be selected and
45
modified only if their layer is editable. Locked layer are displayed
46
in the layer list with a pink background. You can lock and unlock
47
layers from the layer context menu, but note that the active layer
49
<p>A layer may have snapping on or off--objects will behave magnetically
50
only if their layer has snapping on. Layers without snapping are
51
displayed dimmed in the layer list.

52
<p>Layers are also used to create pages that are displayed incrementally

in Acrobat Reader. Once you have distributed your objects over
43

various layers, you can create <a href="manual_30.html"><em>views</em></a>, which
