How to turn off the dynamic prompt?

The dynamic prompt shows the command with the same initiate character, you can choose your command in the prompt box even though you only type some initiate character of your command. This is really useful for people don’t remember the whole command exactly.

But if you think the dynamic prompt is not necessary for you and you want to turn it off, you can find the DYN button on Status Bar. It can be turn off/on by clicking this button.
