Readline maintains what it calls a `kill ring' (the concept is decades
old and the terminology originates with emacs), which commands can add to,
and which can be `yanked' into the line at the current cursor position.
This all basically corresponds to cut/copy/paste and a `clipboard'
as you refer to it.

Look at the readline user manual:

https://tiswww.cwru.edu/php/chet/readline/rluserman.html#Commands-For-Killing

So, for example, in emacs mode, ^K^Y is an easy way to `copy' the text
between the cursor and the end of the line into the kill ring: you kill
the text, which deletes it from the line and copies it to the kill ring,
then immediately yank it back into the line. The cursor position does
move. You can do the same thing for the text between the cursor and the
beginning of the line with ^U^Y.

You can use the concept of the region to copy arbitrary sections of the
input line to the kill ring. Set the mark (saved cursor position) using
^@, move the cursor to where you want, and invoke the copy-region-as-kill
readline command (unbound by default) to copy the text between the point
and mark -- the region -- to the kill ring.
