Spartan includes a text search facility. Select Find on the Edit Menu or type F11.
Type in the text you want to find and press F12
Do not move the mouse while Spartan is searching. Spartan jumps the mouse pointer to the clip it finds containing the text you are looking for so that you can see it in the clip preview window.
If the first find is not the clip you are looking for, press F12 again.
To reset Spartan to the group you were looking at before a search, press Esc.
