rosrun lidar_camera_calibration calibrate_camera_lidar.py --calibrate command not working with ENTER

[Bsting118]

When I run the command, rosrun lidar_camera_calibration calibrate_camera_lidar.py --calibrate, the ENTER key seems to not work when I wish to pause the rosbag record and plot points. I have to manually pause the program using spacebar in the rosbag record terminal and then go back to the calibrate terminal and THEN hit ENTER. This is tedious and might need to be fixed.
