Repetative Feature Line High Low Point

One can modify the CUI to have a command run the high/low point with the same grades. Open the cui, make a new command in the Command List area of the cui. Give it a name you want and add this line in the Macro line in the properties of the newly created command:
^C^CAeccInsertFeatureHighLowPoint;\\\1;1;;
Change the 1's to the two grades you want to use. Drag the command to the toolbar you want to add it to.
