I'm pretty sure there was a recent report that copying worked, but for some reason it included extra bits ignoring the selection.

This works for me in RC 6.

It's random. I can reproduce it in PinJoint3D doc. Couldn't reproduce it in Object. Didn't try other classes.

Seems to depend on selection direction, among some other unknown things.

Perhaps it's that same issue where Ctrl doesn't get triggered sometimes?

Yes, this is reproduced in RC 6 for me too, but it is not reproduced in 491ded1 for some reason.

The problem is somewhere around the first character of the indented line.
If we select a line without indentation, for example Description or Properties (figure 1 in the picture), then everything is copied.
However, there is a peculiarity with indented lines.
If we select an indented line along with the title, everything is copied.
If we select a line and CAREFULLY stop the selection on the first letter (position 2), then everything is copied.
However, if we swipe from the end and swipe the mouse a little further than the first letter (for example, position 3), then nothing gets to the clipboard at this moment.
I found out this back on RC3, but I can't judge why this happens.

PS: So I worked out a solution for myself: if I don't want to aim carefully at the first letter, I copy along with the title.

Edit:This is another issue introduced from 4.0.rc2.
Maybe it's related to this cursor position.

Perhaps this is a RichTexLabel issue, not an editor issue? See also:

Same for me.

Perhaps this is a RichTexLabel issue, not an editor issue

Reading the code looks like it's a RichTexLabel issue, the doc just call the RichTextLabel's get_selected_text method.

String txt;
int to_line = main->first_invalid_line.load();
for (int i = 0; i < to_line; i++) {
	txt += _get_line_text(main, i, selection);
}
return txt;

(Maybe unrelated, the loop starts from 0 looks a little inefficient given that docs are usually long)
