After adding at least one row to the display pane, click to place the times in the two boxes, type different times, and then click Add.

In the Tie Seismic dialog box, hover the cursor over the seismic at the point to tie and click, and then hover the cursor over the correlating tie point on the model and click to tie the two.

Using the Stretch and Squeeze dialog box, click Apply to update the Tie Seismic dialog box.
 

Undo the above activity.

Select the feature closest to the cursor at which to place the tie anchor. In this way, the cursor only has to be near, but not directly over one of the following features in order for GeoSyn to select it:
Peak - the highest amplitude point.
Trough - the lowest amplitude point.
Zero Crossing - the point exactly between the peak and the trough.
None - the tie anchor is not snapped to a feature, but is placed directly below the location of the cursor.
