Is Their an Insert+k in Speakup?

[Chime Hart]

Well, experimenting, typing an insert through an alphabet, when I hit insert+k 
my system seemed to freeze, no speech, no back space beep, so I pushed the power 
button, and booted successfully in to
Linux chime 5.5.0-2-amd64 #1 SMP Debian 5.5.17-1 (2020-04-15) x86_64
I was actually wanting to asign insert+t for tone, but I have no idea how or 
where this is done? I also looked in /var/log/messages, didn't find anything 
strange. Thanks so much in advance for any guidance, or if by accident if I 
found some bug.
