<pre>So I've been investgating a bit more to try and discover why I currently have
my laptop setup with a fake middle button (as you say, the clickpad is just
marked with one line in the middle) and I think I have figured out the
history...
My previous laptop had physical buttons and middle click was emulated when both
were pressed together, which wasn't ideal as it's a bit fiddly for something
that I do very often, but wasn't terrible.
When I replaced it the new one had a clickpad and it seems I discovered what I
have just rediscovered while trying to enable middle click emulation - the
current synaptics X driver doesn't support middle click emulation (by pressing
left and right together) for cickpads!
Having discovered however that I could define custom boundaries to create an
unmarked middle button I went with that, which is also a bit more convenient
than for a common operation like pasting.
I was unaware until just now that clicking with three fingers also did middle
mouse - that does indeed work with synaptics but it's very fiddly.
So if the new libinput driver does support middle as left+right then that's
probably not as bad as I thought it would be, though a fake middle button would
certainly give easier access to middle button functionality.</pre>
