| map is an alias for ‘cl-map’ in ‘cl.el’.

| (map TYPE FUNCTION SEQUENCE...)
| 
| Map a FUNCTION across one or more SEQUENCEs, returning a sequence.
| TYPE is the sequence type to return.

It should be sufficient to eval (require 'cl), i.e. put this line in
scratch and hit `C-x C-e' after ), before you eval that function.

As an alternative, you can put the cursor at a caret and hit
`C-u C-x =',then look for lines after "There are text properties
here:".

HTH.  Best, Arash
