 - **checkpoint**: Target for [checkpoint-controls](/src/controls/checkpoint-controls.js).
 - **grab**: When used on one or both hands, lets the player pick up objects with `hand-controls`. Requires `sphere-collider` and using CANNON physics.
-- **jump-ability**: Allows player to jump using keyboard or gamepad, when physics is enabled. *Not VR-friendly*.
 - **normal-material**: Applies a MeshNormalMaterial to the entity, such that face colors are determined by their orientation. Helpful for debugging geometry.
 - **sphere-collider**: Detects collisions with specified objects. Required for `grab`.
-- **toggle-velocity**: Animates an object back and forth between two points, at a constant velocity.
 - **cube-env-map**: Applies a CubeTexture as the envMap of an entity, without otherwise modifying the preset materials.
-- **kinematic-body**: Constraints player movement using physics. *Deprecated — see below.*

-The `kinematic-body` component constraints player movement using physics, and depends on [aframe-physics-system](http://github.com/donmccurdy/aframe-physics-system/). Using physics for locomotion is not VR-friendly, and often glitchy even for traditional 3D experiences. [Use a navigation mesh](https://github.com/donmccurdy/aframe-extras/tree/master/src/controls#usage) instead, whenever possible.
