If you want to move activities to another measure, Falcon offers you an intuitive way to do this.
Select the activities you want to move by clicking in the box on the left of each row.
Then drag the activities on the measure in the project tree to which you want to move the activities and release the mouse button. Individual activities may be dragged and dropped across measures without selecting them prior. Alternatively to moving by Drag'n'Drop, you can also right-click "Move to..." and select the target measure.
Instead of moving activities, you can also copy them. If you want to know how to do that please click here.
