Hi all, I'm looking for a keyboard for travel that will be quiet enough not to bother folks on a train. Ideally I'd like a mechanical keyboard, but I'm curious what experiences folks have with low-profile switches in a quiet environment. My current daily driver (silent switches, a fair bit of foam and lube, etcetc) is what I would consider office-quiet, but you can definitely hear when I get going and I feel like it'd be a little rude on a leisure train trip.

Right now I'm looking at the nuphy and keychron low-profile keyboards, but I'm open to other options. Currently for travel I use a foldable membrane keyboard so just about anything would be an upgrade.

Does anyone have experience with low-profile keyboards? Are there silent options? Thanks in advance for your help!

Edit: realize I should have specified that I prefer 65 and 60-key layouts for portability.
