You can insert this down arrow either with the "Special characters" panel 
(last list) or as an entity. It's inserted as an operator, but you can select 
the operator element with the Esc (or F2) key and select the Basic element > 
Indentifier entry (shortcut Ctrl m d) to transform the operator into an 
identifier.
