Locking Schedule Dates
To prevent unintentional changes to the horizontal positions of objects on the canvas, the Date Lock mode can be used. Date Lock mode prevents any mouse-based changes to horizontal positions of objects on the canvas; however, if need be, dates can still be changed via property boxes, and all objects can still be moved to different grids.
- Click the down arrow to the right of the Change Display Mode icon from the toolbar.
- Choose from the menu.
NOTE: Pressing the ALT key while moving an object will temporarily enable Date Lock.
