I'm sorry, I wasn't aware that it's already there. At the time of writing there was no such entry in cosmic which is why I assumed there's no such search action.

It seems that it's being ignored and all search actions available in cosmic are taken from here https://git.xfce.org/panel-plugins/xfce4-whiskermenu-plugin/tree/panel-plugin/settings.cpp#n182 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1793393 Title: [Suggestion] New custom command (file search) for Whisker Menu and Application Finder To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xubuntu-default-settings/+bug/1793393/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
