Double Commander

Hello,
I am a very happy fairly new user of Double Commander.
However, there is one mucommander feature that I have not found yet and that I am really missing:

In mucommander, [Ctrl+L] opens the current directory in the default file manager (whatever that might be).

Is there a similar feature available in Double Commander ?
Occasionally I need something like this because it is the easiest way to teach my system a new MIME type.
Thanks in advance for your help.

You can set up a toolbar button that launches the file manager; it should start with current directory. You will have to supply the path to the executable yourself though.
