How to stop displaying the command of a function key?

[LennyNiu]

For the combined keys, Carnac always shows the command name of the key, but I actually don't need that (actually in most time it shows incorrect info because the key may indicate multiple commands, but Carnac only shows a random one). Is there any way to disable displaying it?
