Grid and snap-to-grid functionality is included in Revu to aid in precise placement of markups. The Units and Grid options are available in the Grid & Snap Preferences. Toggle the grid on and off from the Status bar.
When the Grid is enabled, a dotted grid background appears on the page. This grid is a guide only and will not print. Click Grid on the Status bar or press SHIFT+G to enable it.
The grid can also be turned on and off from the Grid & Snap Preferences by selecting Show Grid.
When Snap to Grid is enabled, markups will automatically snap to the nearest grid point. Click Snap on the Status bar or press CTRL+SHIFT+F9 to enable it.
It can also be enabled in the Grid & Snap Preferences by selecting Snap to Grid.
To override Snap to Grid without turning it off, press and hold CTRL while placing the markup.
