I joined an online conference via WebEx earlier this year, made sure my audio/video were muted, and started typing my notes. The presenter stopped mid-slide and called me out because my keyboard audio was interrupting him. I had to un-mute and then re-mute my audio to continue. I know I shouldn't have relied on a software switch when I have a perfectly good hardware disable button, but WebEx embarrassed me in front of dozens of my peers, and I will keep that in mind whenever I get to choose what platform a meeting goes on.
