Missing Time Shift Tool

I’m not able to move audio tracks around. I have a mac and I’m using Audacity 3.1.2. More specifically I want to be able to do what this guy can do at 2:04 in this video

On this link Audio Tracks - Audacity Manual if you press control F then ‘move’ nothing refers to how to move tracks, same goes for the word ‘shift’. I have selected the audio clip that I want to move in the manner of time shift but I cannot move it even after selecting it. If someone could make a video of someone moving clips in Audacity 3.1.2 with Audacity for Mac I would appreciate it.
