What do I use the SemanticsProperty <https://developer.android.com/reference/kotlin/androidx/compose/ui/semantics/package-summary#(androidx.compose.ui.semantics.SemanticsPropertyReceiver).indexForKey(kotlin.Function1)|indexForKey> for? What effect does it have?

I _believe_ it is just there to support <https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/ui/ui-test/src/commonMain/kotlin/androidx/compose/ui/test/Actions.kt;l=166-183?q=indexForKey&amp;start=61|the >`performScrollToKey()`<https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/ui/ui-test/src/commonMain/kotlin/androidx/compose/ui/test/Actions.kt;l=166-183?q=indexForKey&amp;start=61| action in tests> right now.

I don’t see references to it elsewhere, e.g. in <https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/ui/ui/src/androidMain/kotlin/androidx/compose/ui/platform/AndroidComposeViewAccessibilityDelegateCompat.android.kt;l=117?q=composeviewaccess|the accessibility delegate for ComposeView>.

<https://cs.android.com/androidx/platform/frameworks/support/+/14511a46e45e620505a22c007211df14848e436c|The commit that introduced that property> seems to indicate that as well.
