Defines the grid settings for creating and moving objects.
If you have activated the snap grid but wish to move or create individual objects without constraining them, keep the Shift key pressed to deactivate this function for as long as needed.
Defines the snap distance between the mouse pointer and the object contour. LibreOffice Impress snaps to a snap point if the mouse pointer is nearer than the distance selected in the Snap range control.
Specifies that graphic objects are restricted vertically, horizontally or diagonally (45°) when creating or moving them. You can temporarily deactivate this setting by pressing the Shift key.
Specifies that a square is created based on the longer side of a rectangle when the Shift key is pressed before you release the mouse button. This also applies to an ellipse (a circle will be created based on the longest diameter of the ellipse). When the Extend edges box is not marked, a square or a circle will be created based on the shorter side or diameter.
Specifies that graphic objects can only be rotated within the rotation angle that you selected in the When rotating control. If you want to rotate an object outside the defined angle, press the Shift key when rotating. Release the key when the desired rotation angle is reached.
Defines the angle for point reduction. When working with polygons, you might find it useful to reduce their editing points.
