Funny thing is, I have 2 keyboards and a standalone numpad and one mouse, but one of the keyboards registers itself in the system as keyboard and mouse, because it has mouse moving hotkeys. So my system literally thinks I have 3 keyboards and 2 mice. I use a split ergo keyboard for typing. (this one has the mouse stuff) A 65% keyboard for gaming (so I have lots of room for the mouse and don’t have to change the keybindings for the split one) A numpad off to the left so it doesn’t block mouse space, need it for some games and spreadsheets. After a work day is over I shove the split keyboard under the monitor and pull out the gaming one and place the mouse differently. People that visit always comment on how weird that is, but it works for me.
