Error: The operation could not be completed because the selected object is not a transform node. – Accessibility Gap in Viewport 2.0

The error message “Error: The operation could not be completed because the selected object is not a transform node.” appears when a non‑transform object such as a camera is selected in Viewport 2.0, indicating that selection validation does not gracefully handle diverse object types.

Current Maya preferences lack a dedicated Accessibility tab before version 2024.2, forcing users to navigate unrelated panels to enable high‑contrast UI or keyboard navigation, and default navigation shortcuts are not customizable through those settings.

What changes are needed to broaden selection validation for non‑transform objects while preserving existing workflow behavior? How can the Accessibility options be exposed directly in the Preferences dialog to improve discoverability for screen‑reader and high‑contrast users? Can navigation shortcuts be made configurable within the Accessibility settings to support alternative input devices?
