Adding a right click, and setting default extensions
I'm using SUSE Linux Enterprise Desktop 12.
I've installed Sublime Text3, and have made a desktop shortcut using alacarte. I'm using Markdown, and want to make Sublime text the default app for files of extension "*.md"
Is there a config file where I can set this?
(I did try finding Sublime under Open_with -> other application etc. But Sublime is not listed there.
How can I add a right-click open with.. sublime option to the context mouse menu?
