How do I get off the horse? (Minecraft MacBook)?

When I'm sitting on a horse with Minecraft I'm told that I can descend with a left-click, but with the trackpad this does not work. Do I have to change any settings or is there a specific keyboard shortcut?

Same button as the snake. So ctrl

You can go into the water or change the key combination in the settings.

Just sneak

Sneaking is by default Shift left
