In my early teens, I was diagnosed with dyspraxia. I have issues with fine motor control, which mostly affects writing (it's often illegible, and writing for an extended period of time (40 minutes plus) is painful) or actions like cutting up food and depth perception/co-ordination which sometimes ends up with me walking into tables etc. The one accommodation I did accept for it was to type rather than handwrite my college exams (pride did not allow me to do so for my end of school exams).
In the software industry, it doesn't really affect me, apart from occasional embarrassment at a team dinner where an attempt to cut up food results in some going astray, and I consider myself lucky as most people with dyspraxia (I can't remember the exact number currently, but like 70%) also have to deal with dyslexia, something I do not have. I take notes on vim in my laptop rather than on paper like most of my colleagues so that I can definitely read them when I no longer remember them, and shrug off the occasional dropped item or overestimated doorway as clumsiness.
Consequently, most of the time, despite having an actual diagnosis, I answer "no" to this question most of the time. Like the author, the conversation of "but you don't seem disabled" is one I usually wish to avoid, and when you start saying dys- people automatically fill in dyslexia and ignore what you actually said.
