EasySprint adds a sprint keybind to 1.6.4. Hold mode mimics the vanilla sprint key, so letting go of the sprint key while still holding forward won't cancel your sprint like other mods do. Toggle mode lets you activate sprint before even moving, so the moment you press forward you're already sprinting. Type /sprint help to get started.
--- Commands ---
/sprint hold - hold key to sprint
