Yank etc support

[snoblenet]

Nice work, thankyou.

I'd love there to be in-built key bindings to run yank/etc against all matching lines, the current line, or a selected key, value or key-value from the current line.

Unfortunately, this is currently impossible because hl is not a TUI application. It simply processes standard input (stdin) or files and outputs formatted data to standard output (stdout).
For convenience, it automatically starts the default pager (usually less) to display the output.
I considered adding a TUI-like experience, but it would require a lot of work. It's still on my to-do list, though.
