I'll be reading the libinput synaptics and synclient manpages.
I've done this exercise and some tests
ELAN076D: 00 04F3:3244 Mouse id=10 [slave pointer (2)]
ELAN076D: 00 04F3:3244 Touchpad id=11 [slave pointer (2)]
(not sure why it reports twice the same device as touchpad and mouse, there
is no physical mouse attached)
I've no idea, I suppose they are both loaded in case a mouse is attached.
Synaptics driver and libinput (probably the correct, "modern" option).
If I do xinput --list-props for device 11 (touchpad) it returns Synaptics
and for device 10 (Mouse) it returns libinput.
So I am assuming I have to use synclient to get my status.
The current one has just the touchpad, but the lower part of it is
"depressable".
I believe this is what is technically called a "clickpad".
The synaptics man page says that in principle one could set
EmulateMidButtonTime to non-zero to do MB2 with simultaneous MB1-MB3 (as I
was used on the old touchpad-with-buttons) but ClickPads do not support
middle mouse button emulation ... so I gabe up on that.
However looking at the synclient output I discovered parameters
RTCornerButton = 2
RBCornerButton = 3
LTCornerButton = 0
LBCornerButton = 0
so this mean that TAPPING (not pressing-releasing as for the lower area)
in the right-top corner of the touchpad is MB2.
Since I found somehmoiw difficult to locate the exact area of such
corner, and the tap somehow "hard" I decided to ...
... simply SWAP the actions for MB2 and MB3 with
xinput set-button-map 11 1 3 2 4 5 6 7 8 9 10 11 12
This way I can click in the lower right corner to do MB2 (which I use
often in any window to do quick paste, and more seldom in the root window
to call IconMan), while I tap in the upper right corner to do MB3 (which I
use seldom, I can think only of a browser window to get a context
dependent menu)
I'll keep this along with PointerKey assignment to right-control (which
works except in xterms). If I'm satisfied I'll make it permanent.
Thanks in oarticular to Mandar Mitra for addressing me to synaptics and
xinput.
