SnapTap

Makes the most recently pressed movement key win when you hold two opposite directions, instead of cancelling into a standstill.

Hold A and D at the same time in vanilla and the two inputs cancel, leaving you standing still at exactly the moment you wanted to change direction. The SnapTap module makes the most recently pressed key take over instead, so counter-strafing snaps cleanly from one direction to the other.

Axis

Which key pairs to clean up.

Both

Applies to horizontal and vertical pairs alike. The default.

Horizontal

Only A and D. This is a fixed-strength correction, so it will feel slightly less natural than the vertical version.

Vertical

Only W and S. This runs through the game's own movement handling, which means sprint, ice, and speed potions all still apply to it normally.

Disable On Sneak

Stops correcting opposite key presses while you're sneaking. On by default, so precise sneak-edge movement behaves exactly as you'd expect.

Only On Ground

Only corrects opposite key presses while you're standing on a block, never mid-air. Off by default.

Recommended: leave Axis on Both. The vertical correction is the more natural of the two, and there's no reason to give up the horizontal one unless A/D feels off to you.
