Run file in console in jupyterlab?

[taiya]

How can you run a (e.g. Python, Julia) file in a console?

Right now there is a "create console for editor", but what if you already have a console open and you simply want to re-execute the file content?

The only solution I can see is to first Select All, and then Run Selected Code

Any better way?

I'd probably use the keyboard shortcut to select all (ctrl/command a), then the keyboard shortcut to run the code (ctrl/command enter, I think).

@jasongrout that's exactly what I said in "the only solution" but it is a pretty weak solution.
Think a-la MATLAB (which julia tries to replace), there you execute a script in the console by just pressing F5?
