Cannot control using keyboard

[ChienVT]

Hi,
I followed section 2.1 about "Walking demo in RVIZ", it seems that using the keyboard doesn't work. Can anyone run? Please help me, it doesn't return any error. Everything else is fine.
Thanks.

Hey @robo4869, you have to press and hold the keys for it to work
