Nice! I was just thinking of looking at this, and then you already did it. :)

Although, I would also add this:

diff --git samsungctl/interactive.py samsungctl/interactive.py
index d6c2e21..c882497 100644
--- samsungctl/interactive.py
+++ samsungctl/interactive.py
@@ -10,6 +10,7 @@ _mappings = [

     ["KEY_BACKSPACE", "KEY_RETURN",        "Backspace", "Return"],

     ["s",             "KEY_SOURCE",        "S",         "Source"],

That is, include the key to the samsungctl/iteractive.py.

Agreed. Will update the PR with this code
