@Shulem If the extension is a playfile - you need to define in the extension like this:
control_play*=go_to_folder
playfile_control_play_*_goto=/1/30
But if the extension is a menu - you will need to define in the ext.ini file like this:
star_extension=yes
text_extensions=yes
And create a file in the extension called ExtensionNumbersAndAssociations.ini and define in it like this:
Star=/1/30
