Toggle Sneak & Sprint
by Nischhelm
Toggle Sneak & Sprint lets players hold a key briefly to keep sneaking or sprinting on Minecraft 1.12.2, without holding the button down.
What it does
Pressing the sneak or sprint key once switches the action on, and pressing it again switches it off. The behavior follows what newer Minecraft versions already offer, applied to the 1.12.2 controls. Sneaking can also end automatically when sprinting starts, which is controlled by a setting.
Several parts of the mod can be adjusted in the game. Settings for the toggles and the sprint behavior are reachable from the in-game options, so a player can change them without editing files. The mod also fixes sprinting so that it does not boost flight speed while the player is flying.
The mod is built for Forge 1.12.2 and runs on the client alone, so a server does not need to install it. Files are released under the Apache License 2.0, and the source code and issue tracker are public. The latest file, v1.1.3, was published on 2026-03-15.
Key features
Toggle sneak
Tapping the sneak key turns sneaking on or off, so the player does not need to hold the key down.
Toggle sprint
Tapping the sprint key turns sprinting on or off for as long as the player keeps moving.
Automatic unsneak on sprint
An optional setting ends sneaking as soon as sprinting starts, so the two states do not overlap.
In-game settings
Toggle options are changeable from inside the game and take effect without restarting.
Flight speed fix
Sprinting no longer increases the maximum flight speed while the player is flying.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Long walks and exploration
Players who travel across large areas can leave sprint switched on rather than holding a key for the whole trip.
Precise building
Keeping sneak active lets a player stand near ledges and edges while placing blocks.
Who it’s for: Players on Minecraft 1.12.2 with Forge who want toggle controls for sneaking and sprinting. Because it is client-side only, it suits single-player and multiplayer players alike, but server owners do not need to install it.
