Converting selected variable by hot key

Hello!
As far I remember in prior versions of PhpStorm there was a function
when selecting some variable, like
$services_last_sitemapping_results
with hot keys it could be rendered into
$servicesLastSitemappingResults
or some other convirting.
Similar functionality for string constants.
I did not find anything like that in PhpStorm 2019.1.2
has it ?

Thanks!
