Thanks for "language-context”.

what are the key shortcuts to compile the context file at hand?
i try the atom editor on Linux platform.
Can't find the way to feed the tex file into context luatex...

There are no key shortcuts. I use a terminal.
As I wrote:

So there’s no run command or something like Atom-LaTeX

When I use Atom for ConTeXt, I use the package,”process palette” in which commands and a key shortcut are defined. By pressing the defined key-shortcut, terminal will do the job as Hraban said.

Best regards,
