hector_quadrotor not hovering while using teleop_twist_keyboard

[sandilyasg]

How do I get hector_quadrotor to hover while using teleop_twist_keyboard? As in what code do I have to change to allow this, because in the noetic version when you use teleop_twist_keyboard and hit 't' to gain altitude, once you let go, it stays at the same altitude, hovering. I understand this is because there are commands being sent to keep it at that level, so I was wondering what code do I need to change in the melodic version to enable this.
