I've always used a mouse and when they became available more, a keypad. Gone through the Razers and logi ones and now have the best (imo) I've come across which
is this . More or less every key is mappable/macros, not had a keypad like it, its also a mechanical keypad, so feels good too.
When I was younger, I played with small tables (height adjustable), to my left and right. I had a nice relaxing office style chair (very nice one).
KB, then later Keypad on the left and mouse on the right. Just the way I game. Keyboard to the front is only for work/typing, never really touch it for gaming.
Lazy gaming mode, is what my kids always use to say. But when I got in from work and wanted to relax, I'd spend money on finding the right stuff to use that made me comfy. [yesnod] Although a seperate room to game in, was also nice. I have my 'den' now, the wife's idea of keeping me out of her way, now we're together much of the time..
Forced retirement.

But it gives me lots of time for doing other things..
