File Manager keyboard shortcuts limited to core actions in cPanel 12.x

cPanel File Manager documents keyboard shortcuts for common file operations. The documented shortcuts enable some actions without a mouse.

The current scope of keyboard operability is unclear for the full user-facing workflow. Interactive elements such as the context menu and sidebar tree are reported to lack comprehensive keyboard navigation, and dynamic elements like modal dialogs and dropdowns may not be consistently announced by screen readers. ARIA roles are applied to primary controls, but coverage for dynamic UI is uncertain.

No public roadmap or specification for extending full keyboard support to all UI components has been identified, leaving compatibility expectations unresolved for keyboard-only and assistive-technology users.

Is full keyboard navigation supported for the File Manager context menu and sidebar tree in cPanel releases up to 12.x? Is there a documented specification or roadmap for extending keyboard support to all interactive elements? How should modal dialogs and dropdowns be expected to behave for screen reader announcement?
