Key binding to an external program (Marked on mac) so that current file opens in that program



I’m new to using Atom and I’m trying to move from TextWrangler to Atom. One very useful feature of TextWrangler is to allow menu driven applescript calls. I have one that allows me to open the current file in Marked ( The built-in Markdown view in Atom is great but Marked allows me to export to pdf/html/etc… .

I came across this article (Open file in external program from Atom) that has some useful packages. However, I’m not opening a file that is not supported. I just want to open the current supported file in another program (i.e. Marked). I tried using the open-file-in package but that didn’t work for me.

I’d appreciate any information.

Thanks for your help.
