Cursor is a lightweight abstraction that tracks and manipulates a position within a data stream or text editor, handling caret rendering, movement, and selection. It exposes a simple API for setting and querying the current index or row/column, moving in all directions (left, right, up, down), and adjusting the selection range. Support for multiple cursors enables parallel edits, while snapping, scrolling, and viewport-aware updates keep the cursor aligned with the visible region. Rendering integrations provide visual caret appearance and blink behavior, and the API is designed to be editor-agnostic, allowing plug-ins and adapters to implement custom behavior.
