switch quickly between default classification labels (image segmentation)

[Wafaa-arbash]

switch quickly between default values. Expected user case : I have two labels, "Cat" and "Dog", and I want to create the bounding boxes for the cats first and then for the dogs. I select the default value "Cat", I create my bounding boxes without selecting the label (I press "b" to create the bounding box, I create it with the mouse, and then directly I press "Enter" to validate the creation), then I select the default value "Dog", and I create my bounding boxes for the dogs.
