StepUp allows you to walk up one block height without jumping.

This is a client sided mod.

It works on both Singleplayer and Multiplayer servers. Press "H" to switch between modes in-game. The key-bind can be changed in the controls menu.

 
StepUp for Minecraft 1.10+ allows the player to cycle through 3 auto jump options using the StepUp keybind.
1. StepUp Activated
2. StepUp Deactivated
3. Vanilla Auto Jump

StepUp 1.14.4+

1. The default key-binding has been changed to "H" key to not get in the way of Journey Map key-binding
