Hi. I've been using my trusty Model M for many years now.
Recently the right shift key has started sticking - as in, it physically stays stuck down, or is just sluggish to spring back up.
I have fairly small hands so I'm usually pressing on the left 1/4 of the key, and I tend to slide my finger to the left as I press it, which causes the key to tilt slightly.
My suspicion is that it's an issue with the circular support post, but cleaning it hasn't helped at all. I've even tried lubricating it, which has helped a bit, but it's still sticking.
I'm wondering if anyone has experienced a similar issue? Any tips what the problem actually is, and how I might solve it?
Thanks.
