As for this, I get a combination like Mod2+Mod4+ d for the mouse button press. But when I put this in to the .xbindkeysrc like for example:

#Mozilla
“firefox”
m:0x50 + c:40
Mod2+Mod4+d

It doesn’t work with the mouse button and I just keep getting a “d” everytime I press the button. Nevertheless if I press the keyboard key Super_R + d it does open firefox. But if I press the key Super_L + d it doesn’t. I managed to notice that pressing Super_L + d + d (pressing d repeteadly twice) opens firefox.

Somehow this mouse button is linked to my Super_L physical key. when I press Super_L by itself, it show’s the activities overview (the same as alt+F1 in the keyboard shortcuts, or going with the mouse pointer to the upper left corner activities menu). I did try the keyboard layout distribution map, to see which keys highlight when I press one on my physical keyboard. I noticed that when I press the right Super key, control, alt, etc, the appropriate key highlights on the map. Nonetheless when I press the left Super key it doesn’t highlight any keys on the layout map.

I do have xmodmap but haven’t done anything strange with it. This is the output I get when running xmodmap and seems to be fine.

xmodmap: up to 4 keys per modifier, (keycodes in parentheses):

shift Shift_L (0×32), Shift_R (0x3e)
lock Caps_Lock (0×42)
control Control_L (0×25), Control_R (0×69)
mod1 Alt_L (0×40), Alt_R (0x6c), Meta_L (0xcd)
mod2 Num_Lock (0x4d)
mod3
mod4 Super_L (0×85), Super_R (0×86), Super_L (0xce), Hyper_L (0xcf)
mod5 ISO_Level3_Shift (0x5c), Mode_switch (0xcb)

If you could help me with this, it would be great.
Thanks in advance for your help.
