scroll.evemu.2017-05-19 three recordings

I have "sudo evemu-record --autostart=3 /dev/input/event5 scroll.evemu" running
in a shell, and in another I have "watch ls -l" on the dir containing these
files as they're created.

When I'm typing, I have absolutely no ability to record in my mind what I'm
doing mechanically with my fingers. Once these files appear, I try to replay
history in my mind, did I intentionally use the trackpad? Did I have to move
the cursor somewhere? I have literally no idea, it's simply not how my mind
works.

So these three events? Are they intentional? Or are they stray palm touches?
I'm pretty sure they're stray palm touches because at the time I was typing I
had no reason to move the cursor positioning. But I can't tell you with any
certainty because I have zero mechanical memory of what I was doing; only the
thought of what I was writing. It's probably the same thing as having a
conversation with someone, and then asking them about the position of their
tongue 5 seconds ago. They'd say, what? And then they'd have to think about
what they were saying and what the position their tongue was in, and then
they'd forget the whole thing. There's just no awareness of the mechanics as
it's happening.

And I have no ideas how to increase the certainty other than setting up a video
camera to simultaneously record my hands typing as well as the screen with
"watch ls -l" running, and match files to movements, but I have no way of doing
that.
