- 
                                                    Using the command line, enter "linking-method-switch" 
- 
                                                    Use the quick key combination "tlm".

                                                    Display the Find Command screen, locate linking-method-switch and click Run. 
Description
Toggle between optimal and sub-optimal (fast) string linking methods.
- 
                                                    If turned ON, when linking strings the wireframe is created optimally with the best surface being selected from those that satisfy the linking criterion. 
- 
                                                    If turned OFF linking is done with tag strings - either provided by you, or if none exist then the closest pair of points on the two strings after translation to a common centre of gravity will form an implicit tag string. Each pair of tag strings is linked independently. The speed advantage of the sup- optimal increases with an increasing number of string points. If the sub-optimal method fails then linking will default to the optimal method.
