Just tap F, instead of holding it. Holding it brings up the equivalent of a context menu, like right clicking in a 2D application. Some items have more than one action, rather than make you open up a dialog to pick from a list of actions, they tried to simplify it into the context menu. For what it's worth, the actual design goal is that most things are in-world buttons or screens, and that the context menu is less necessary.
