StickierKeys

The only two features this simple mod adds are two keybinds to enable auto-walking and auto-running:

• Z (configurable), which enables or disables automatic movement entirely. Press this key while moving or standing still to have the mod "hold down" the walk key for you.
• X (configurable), which toggles between automatic walking and automatic running. Press this key to additionally have the mod "hold down" the sprint key for you.
