Magnifier tool magnifies area under the mouse cursor. You can specify how big the magnifier will be (in &lt;span style=&quot; font-weight:600;&quot;&gt;logical&lt;/span&gt; pixels) and how much it will zoom.&lt;/p&gt;&lt;p&gt;By specifying &lt;span style=&quot; font-weight:600;&quot;&gt;undo/redo&lt;/span&gt; step count, you can control how many undo/redo steps is available when editing document. Set maximum undo step count to zero to disable undo/redo. You can also set undo step count to nonzero and redo step count to zero. In this case, redo actions will not be available, only undo actions. Changes are optimized for memory usage, so each undo/redo steps shares common unmodified objects between them (so, by guessestimate, 10 modifications of 50 MB document can take 51 MB of memory). Memory usage depends on how big changes are, but usually only small changes are done (for example, editing form field, modifying annotation affects small number of objects).&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</string>
