What does Ctrl+Click do?

Hi all,

I have a codemirror 5.65.10, and I have added some bindings for mouse up that actually examine selection.

I was doing some tests, and I realised that instead of clicking, if I use ctrl click, the output is strange, the selection seems to include something (the string is a series of \n, from one to multiple).

Is there a mapping for ctrl-click, I failed to find in the documentation?
If yes, what is supposed to do?

Regards,

George

It creates a new cursor, as part of the multiple-selection feature.
