If you want less travel on your mechanical keyboard, you can use o-rings on the switches. Also dampens the sound when bottoming out. I personally use one per switch, but you can also go for two rings per switch which gives you laptop-like travel.
It killed one of my DAS actually using those. Not sure what happened, the controller just stopped working and I was told "that happens". And I found later (with a new one) that I much preferred it without those, it felt like a manual clutch on an automatic car.
It's like how something breaks after changing the wallpaper? ;) Cherry blacks swear by o rings because of the no-bump typing.
