Sure you can. And you can use a lot of datatypes for keys. You don't
want to use numbers (integer! and decimal!) because those will be
interpreted as positions (e.g. for use with PICK), not keys.
my-select: func [series [series!] key] [
hash-ser: make hash! [<a> [1 2] <b> [3 4]]
my-select hash-ser <a>
series: [#"z" $2.2 3x3 a <b> #c %file-d [name--host--dom] http://www.test.url #"z"]
foreach key series [
print [key tab series/:key]
