I'm playing with it now, in Notepad.
I noticed that after issuing the command,
hitting space will bring up the panel quickly.
If I close the panel with ESCAPE, and then issue the command it comes up but closed. Hitting space will open it.
I'm still floundering about trying to
consistently get into a list of the emoji symbol for smiley
Tabbing will get me to the list of groups,
arrow right goes through the groups such as:
Most Recently Used and smiley faces.
But, how to open or get into the group list
of Smiley Faces?
Just once did I land in a list of smiley
faces but I don't know what I did.
