Look for an alias called slice, it will be either in the remote scripts titled 'alias slice' or 'alias -l slice' or it will be in the aliases just called 'slice'
example of a custom identifier
alias testing { return testing testing 1. $1 2. $1 3. $1 }
on *:text:!test *:#: { say $testing($2) }
<somenick> !test yo
<yournick> testing testing 1. yo 2. yo 3. yo
