Looking for the PHPStorm selection keybinding

What is the default keybinding for selecting a higher instance on Mac? For example if I have the line someFunction($array = ['something' => 'else']) and my pointer is on the word else when I press this combination I expect the 'else' to be selected if I press it again ['something' => 'else'] will be, if once again then $array = ['something' => 'else'] and so on.
