It means all HTTP verbs: GET, POST, HEAD, PUT and DELETE

The verb list can be either a comma-separated list of HTTP verbs (for example, "GET, PUT, POST") or a start-script mapping (for example, the wildcard character * [an asterisk]).

It means that the handler will execute for all verbs - ie. GET, PUT, etc.

It can be used to specify that, for example, a certain handler should only process POSTs not GETs.
