While using visidata, I tried to copy the content of a cell. I tried it a few times, but it did not work. I thought that the cause could be my terminal, or the fact that I run wayland.
I though about opening an issue for that, but since nobody had the same problem, I went to look at the code.
Only at this point did I realize that "clipboad" meant internal clipboard and not system clipboard, just like in vim. It did not cross my mind it could be the case.

For that reason, the docs should clarify the distinction between both, in particular in the command descriptions.
