Today I've realized that my Modern Beige keyset have different key profil for F and J key.

My J key have deep dish profil but not the F key..
Do you have the same issue ?
Nope...although I have a different issue, the keycap stems are too narrow and won't fit on the side-mounted switches in my G80-5000...I know, very first world problem
Attempting to measure anything switch-sized with typical digital callipers gives random readings, but the Cherry MX keystem measurements are roughly 1.25–1.30 mm for the width of the left and right cross arms, and 1.05–1.10 mm for the width of the front and back cross arms. You can see this clearly by looking at a switch.
More information at the next episodeHi Damien,
Thanks for your email and the picture. I'll have to double check the sets we have to see if it has the same problem. I'll get back to you as soon as I figure it out. Sorry for the inconvenience.
Thanks,
Wendy
