How to select (copy) a line in nano?

Question

Debian

It seems to be a ridiculous question, but I can’t cope, and googling didn’t help (suddenly!)
In the file, the line without a transfer goes beyond the visible part of the screen, and I select with the mouse only what is visible. Accordingly, it is copied ..
And how to select (copy) the entire line?

The Ctrl+K combination cuts the line and it can be copied in the same file, but this buffer is not transferred to another putty window, and I need to transfer a line from one file on one server to another server

Answer 1

m+6 Copy the current line and save it to the clipboard

Answer 2

> but this buffer is not transferred to another putty window
Select a line with the mouse in one putty window;
Switch to another window;
Use the cursor keys to position the cursor at the desired location;
Press shift+ins or RMB to paste.
It if in a forehead for putty.
