Pycharm Custom URI Schemes

From any browser, I can type and hit Enter:

pycharm://open?file=file_path

or, programmatically, call:

window.open('pycharm://open?file=file_path', '_top')

This will open PyCharm at the specified file, which is very handy. I learnt about this possibility from word of mouth. Interested in learning more about this kind of links (perhaps the link can be augmented with the desired file line number?), I tried to look for documentation on PyCharm's website pertaining to it, to no avail.

As such, can someone point me to documentation about PyCharm's Custom URI Schemes? Alternatively, could you let me know of any other Custom URI Schemes that exist?

Thank you.
