Support tab indentation in py-editor

[MarcSkovMadsen]

I've just tried using the py-editor. When I'm changing the code inside the editor I would expect tab to indent my code. But instead I jump to some other html element on the page.

Please support tab indentation and shift+tab dedentation. And probably more keyboard short cuts.

Personally I would prefer all my normal VS Code keyboard shortcuts to apply 😄

Capturing tab breaks default accessibility and screen navigation, unfortunately. I don't think it explicitly violates WCAG, which provides guidance for instructing the user when an alternate key should be used to navigate out of content, but I'm not sure it's something we as PyScript should do out of the box...

Just my opinion; from a technical standpoint it's not too complicated to implement.

how might someone implement this? i've spent a bunch of time trying to figure it out (ie, diving into the specifics of what seem to be a CodeMirror implementation) but have not had any luck. interested in binding to ctrl-tab or something, as an option, to avoid breaking accessibility

Here is how CodeMirror handles Tab: https://codemirror.net/examples/tab/. That could be used as inspiration.
