The main screen is 2 if one other screen sits to its left.

Parameters #

Takes 0 to 1 argument. {{ screenIndex(text?) }}

Examples #

screenCount() > 0 ? screenIndex() : 0

screenCount() > 0 ? screenIndex("last") : 0

Gotchas #

• A screen that doesn't exist is an error: screenIndex() found no screen 'Studio'. With no screens to read (a test run, a fake system) it always is, so check screenCount() first.
