Wish Code Editor tabbing

If you have code editor tabs in separate groups (horizontal or vertical) and you right click on one of the tabs, you get an error message that says
I suspect that an exception was thrown by the target of the invocation.

But that's not my wish. I wish that the same module could appear in multiple tab groups. I'd like to be able to, for example, work on a sub at the bottom of Main while seeing a sub at the top of Main as a reference. Or work on two different subs in the same module simultaneously even if they are much farther apart than one window length. This would be possible if I could open the same tab in two different tab groups.

You can use the split feature to see different views of the same module:

I'm not seeing how to get that configuration.

If you right click on the modules, you can select Float and the code editor window will become a separate window/form. Do the same with the other modules and then you can arrange them as per your needs. I think this is what Erel is intending..

All that is quite obvious. For what I was wishing and what Erel is claiming is that you can create a split window in one module (i.e. edit two different parts of a single module at the same time, in two separate windows) and I'm not seeing how to do that.

Sorry, then I misunderstood. Yep, I can't find a way to do that as well...

Yes, it's very mysterious. But Erel's picture clearly shows it happening.

You must move down the small rectangle, just below the zoom level.

So it is. Wow, was that obscure. Surely that functionality would be better placed in the tab's context menu.
