# Description

This MR swaps the keyboard command (X, Z) for yaw in the `Se2Keyboard` class
to have the following mapping:
- Z - positive yaw
- X - negative yaw

It also corrects the docstring of the `Se2Keyboard` class.

Fixes #1029

_Note:_ I double checked the `Se3Keyboard` class and the implementation
there is correct.
