tui: allow to paste using mouse middle click

[yennor]

Issue

When using the tui on a linux console one can only paste text using ctrl-shift-v, but not the middle mouse click, what would also be standard in most linux desktop environments.

Version and model info

cecli v.0.95.11

As in the other post, I think textual requires holding the shift key, so shift right/middle clock should do what you want

as in the other post, i don't think anybody would guess that.
Maybe a short notice, like the one about "enter to submit, shift+enter for new-line" would help?
