Show Tool-Tips

Determines whether Tool-Tips (short help texts next to the mouse cursor) should appear.

Activate mouse wheel zoom

Determines whether the mouse wheel should directly zoom the illustration or whether it should take on the normal scroll function. If this option is not marked, the illustration is enlarged or reduced by turning the mouse wheel while the Crtl key is held down.

The activated mouse wheel can be used in an active window only. To activate a window, simply chick somewhere within the window.

Activate the Pan-function

Determines whether the Pan function is activated when clicking on the middle mouse button. "Pan" is a function that moves the visible section of the application window without changing the illustration size.

Extended selection mode

The extended selection mode is dependent on the position of the start and end point. If the start point lies left of end point of the selection rectangle, then not only all objects located within this rectangle will be selected, but also objects that are crossed by the selection rectangle will be marked. In the normal selection mode, only objects lying completely within the selection rectangle are highlighted.

Constrain angle

The entries are limited to whole-numbered multipliers of the selected element angle.

The constrained angle is activated by keeping the Shift key held down.
