It can either be freely positioned and sized or fixed. The choice between the two is made in theSmart Tilt Control Panel. The display contains two essential elements, the menu and the display itself.The main functionality of Smart Tilt resides in the menu of the display window.5.5 The displayThe window will display a schematic representation of the <strong>Tecnai</strong> viewing screen (but in gray instead ofyellow to reduce ambient lighting near the microscope).MenuThe menu gives access to all Smart Tilt functionality.Toolbar buttonsToolbar buttons giving rapid access to often-used functions can be found on the left-hand side of theSmart Tilt display (the display of the toolbar is optional). If there is sufficient room the buttons will belarge, otherwise they are small (as shown here). From top to bottom the buttons are Full tilt, Bragg tilt,Left, Right, Switch direction, Undo, Redo, Tilt step, Focus and Defocus.DisplayThe display is a representation of the viewing screen of the <strong>Tecnai</strong> microscope with its inscribed circlesand plate markers. On top of this, Smart Tilt displays the tilt axes in their orientation and circlesrepresenting tilt angles. The tilt axes are shown in red, the blue circles on the screen mark tilt angles andthe green line (if present) marks the direction of the diffraction spot used for Bragg angle tilting.Convention: The direction of the tilt axes (+/-) is displayed in such a way that the center of a Laue circlewill move in the direction of the marker on the screen if that particular direction and sign of tilt is chosen.
