How can I send comma before down in Autohotkey (AHK)?

Question

I want to make an AHK script to do the following:
After writing a hotstring, repeat for ever:
Send a comma
Send down arrow
My current code is this:

::startthisthingnow::
while True
    Send, {,}
    Send, {Down}

But it only sends unlimited commas after each other, like:
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

Answer 1

Either place all sends in one line:

Send, {,}{Down}

or include the second Send in the loop:

while True{
  Send, {,}
  Send, {Down}
}
