Minecraft – How to turn off the fast walking ability in the smart moving mod

You seem to have uncommented some lines that should have remained as comments. "Uncomment to enable mod" actually refers to the line below it ("modCheatEnabled = yes").

Every time there's a blank line, the first line afterwards is a brief description of what the option does and so should remain as a comment.

So, for example, the first couple of lines originally look like this:

# Uncomment to enable mod:
#modCheatEnabled       = yes

You changed it so it looks like this:

Uncomment to enable mod:
modCheatEnabled       = yes

But it should actually look like this:

# Uncomment to enable mod:
modCheatEnabled       = yes

The "modCheatEnabled" line should be the ONLY line you remove a '#' from in the Cheat Mod section of the config. I noticed that several other options (presumably all the options you changed) have been uncommented in the same way. "Toggles Cheat mode on / off", "Show / hide ores", "See through everything nearby..." and all the other lines that look like descriptions should still be commented with a '#' sign in front of them. It's the lines below those comments ("keyCheatShowOres = C", "keyCheatSee = T", etc.) that actually do anything.

To turn off the speed keys set move.speed.user to false in your configuration:

move.speed.user:false
