If you have an autoreturning artifact wielded, and nothing quivered, using the ‘f’ command will throw the artifact, without making you have to use the t command then select its inventory letter.

Artifact shuriken The Silver Star: deals +d8 damage to all targets. Like Mjollnir, it returns to the player’s inventory after being thrown, but doesn’t have any chance of hitting the player. Since there is only one of it, it cannot be multishot.

This would be a good first sacrifice gift for Monks.

Arrows fired from The Longbow of Diana will never break and will automatically return to you. It also counts as your racial bow regardless of your race.

The Heart of Ahriman returns to your quiver when slung. Or at least add some returning sling-ammo artifact.

Artifact arrow that auto-returns to your pack and cannot break. But there is only one of it, so it can’t be multishot.
