Using ubuntu, and mathematica 11.1, the keyboard shortcut ctrl+g creates a small emoji of an old landline phone (see image). It does not appear in mathematica 10. If I copy it from 11.1 end up with the string "\.07" in my clipboard.
It can not be set equal to anything, I get the error message:
Syntax: Expression cannot begin with ... = 5
It also doesn't seem to be useable in any function, I get the error message:
Syntax: f[...] is incomplete; more input is needed.
where the ... is the symbol.
Does anyone know what this thing is, and why it was given this shortcut? It seems rather mysterious to me (and my colleague who originally found it)!
