Thanks to Omakub I got introduced to Zellij:

Zellij is a terminal workspace. It has the base functionality of a terminal multiplexer (similar to tmux or `screen) but includes many built-in features that would allow users to extend it and create their own personalized environment.

This is how a Zellij window could look like, showing the output from /var/log/syslog

Now we want to copy this part (in the last line of the output) using the keyboard only:

2024-09-28T06:56:13.403642+02:00 aetron kernel: [UFW BLOCK] IN=enp14s0

First press CTRL+SHIFT+SPACE to enable the vim mode in Zellij.

Then navigate to the first char you want to copy using the cursor key:

Now press v to enable vim Visual Mode (nothing will change visually).

Now move the cursor to the right until the char you want to be copied last.

Finally, press y and this will yank you selection and it will be available in your clipboard for further usage.

Great, but there's one issue: multiline selection:

As you can see, the green border is included in the selection and this will mess up you copied content.

But there's a solution for that:

Press CTRL+p, then z to disable the border before you're entering vim Mode:

Now you can copy multiple lines without including the border.

If you want to get the border back, press CTRL+p, then z again.

Instead of using Visual Mode, you can also enable Visual Line Mode by hitting V instead of v and that will allow you to just select full lines by moving the cursor up and down.
