'S' keypress happening often on laptop

On laptop but using an external usb keyboard. Key presses of 's' will just start popping up randomly now and then for about 20 times on short succession then might stop again. Not sure what causes or makes it cease again.

Since I have also had issues with phantom clicks with the touchpad, which I have floated and that issue seems to have stopped, I am guessing the keypresses are probably from the laptop keyboard though not 100%.

I tried doing xinput list then xinput float 18 for AT Translated Set 2 Keyboard which I read online would kill the laptop keyboard however the keys still produce output even though xinput list then says it is floated.

Here is my xinput list:

⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ TypeMatrix.com USB Keyboard Consumer Control	id=14	[slave  pointer  (2)]
⎜   ↳ Logitech M315/M235                      	id=15	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Video Bus                               	id=6	[slave  keyboard (3)]
    ↳ Power Button                            	id=7	[slave  keyboard (3)]
    ↳ SIGMACHIP USB Keyboard                  	id=8	[slave  keyboard (3)]
    ↳ SIGMACHIP USB Keyboard System Control   	id=9	[slave  keyboard (3)]
    ↳ SIGMACHIP USB Keyboard Consumer Control 	id=10	[slave  keyboard (3)]
    ↳ TypeMatrix.com USB Keyboard             	id=12	[slave  keyboard (3)]
    ↳ TypeMatrix.com USB Keyboard System Control	id=13	[slave  keyboard (3)]
    ↳ Intel HID events                        	id=16	[slave  keyboard (3)]
    ↳ Intel HID 5 button array                	id=17	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=18	[slave  keyboard (3)]
    ↳ TypeMatrix.com USB Keyboard Consumer Control	id=19	[slave  keyboard (3)]
∼ SIGMACHIP USB Keyboard Mouse            	id=11	[floating slave]

As an aside, why would the system touchpad be called USB keyboard mouse? It has certainly stopped the laptop's touchpad but unsure why it would be called usb.

EDIT: Ah.. following that reasoning I just tried to float 8, and that has stopped the laptop keyboard. I will try adding it to .xinitrc.
