[adamgaox]

what's the difference between sum({$*< and sum({<?

[oknotsen]

If you remove the star, there is no difference.

With star, I don't know.

If you are using alternate states,

{$< ... will reference the default state, while {< ... the inherited state

[effinty2112]

{$*< ...>} will return a set that is the intersection between $ and <...>. $ is the set of selections in the document and this character can be omitted because this is the default set. So can remove $* from {$*< ...>} to leave only {< ...>}.

Sweet. I did not know that. Thanks!
