How to overload same key to have different effect based on host/url?

[limaceous-bushwhacker]

Title. I'd like to map yy to copy different URL based on site. Currently I get error that yy has already been mapped if I use the following format:

env xx host="site.com"
map yy action sed="pattern"

If I change the host and env name in this, it says yy has already been mapped.

EDIT: Piggybacking off of this discussion, can we fire off two sed pattern on a URL? Something like sed="0,1"

env only names a environment which may be used by runKey - see https://github.com/gdh1995/vimium-c/wiki/Map-a-key-to-different-commands-on-different-websites :

env xx host="***"
map yy runKey expect="xx:yy1,xx2:yy2,xx3:yy3" default="yy0"
map yy0 command0
map yy1 command1

You may just write sed="01" to use both 0 and 1:

• a simple sed key's name should only have single character, so long values means to apply multiple sed keys in the same time
• if you want to give a substitution rule a longer name, then the name must:
  • start with the _ (underscore) character
  • should not be longer than 8 characters
