I've found the MS Comfort Curve 2000 keyboard to be very light touch.
I tried quite a few on the store shelves before deciding on it.

The keys are almost flat like a laptop, but not as crowded together like most laptops.
And it got stuff spilled into it 2x so far & just a good rinse w/warm water and drain & then a bit of blow dry a day or 2 later good as new.
I kept my older kboard for these fill in times.


I'm ordering another one since the price has come down a lot.
