Ctrl+Numpad Minus and Ctrl+Numpad Plus zooms in and out. Make sure to use the CTRL or CMD(since it looks like you’re on a mac) if you use just numpad plus/minus you will speed up slowdown the framerate. Holding shift key down will show frame rate in bottom left corner along with filename. I like to use I sometimes just to see play cursor in the player. you can also use the arrow keys to go frame by frame. left and right is 1 frame and up and down is 10 frames. Shift+Left/Right is start and end. You can also use LMB drag to scrub thru it.
