# Cursors
Cursors in Marple Insight are used to display the values of visualized signals at specific points on the time axis.
When a second cursor is added, Marple can perform calculations between the two.
Marple can calculate the difference, minimum value, maximum value, and mean between the two cursors.
### **Placing a Primary Cursor**
Simply click on the desired point in the time series plot to place the cursor.
### **Placing a Secondary Cursor**
Hover over the plot and press the **Space bar**, or click the "Enable Secondary Cursor" button in the toolbar above the plot.
To remove the secondary cursor, press **Escape** or click the secondary cursor button again.
### **Calculations Between Cursors**
These results are displayed to the left of the plot, between the primary cursor (solid line) and the secondary cursor (dotted line).
