Most of the time when I'm coding I use the keyboard to jump to symbols. But when you are getting acquainted with a large codebase, reading through and clicking to jump to symbol can be a more efficient way to parse the code and understand its interdependencies.
It may depend on what you use to position the cursor as well — I haven't used anything but a trackpad in the last five years, and even on that mostly I use gestures to navigate UI. Since the trackpad is almost part of the keyboard it feels very seamless to scroll/tap and type.
Yeah, I'm much more likely to bump a trackpad than reach for a mouse, even when the mouse gives me much more control (I always find trackpads a little finicky), just because of the distance. My hands don't need to actually go anywhere.
Of course, I also bump the trackpad accidentally sometimes, but that's a separate issue...
