When editing scripts, they are similar to visemes except for their appearance, which are in the form of flags and not boxes.
Point the cursor on a script and it will turn into a hand. Click it twice to call up the editing dialog box (go to #2) or once and right click on it to Edit, Delete, or Remove All.
If you choose Edit, a dialog box will appear. After you have finished selecting another script or have modified the Argument String, click OK.
You may also go through the menu HAP > Edit Selected > Action. Click OK after you have modified it.
