i m assuming that the tmux prefix is Control+b and that you have emacs
style key bindings on
1) enter copy mode using Control+b [
2) navigate to beginning of text, you want to select and hit Control+Space
3) move around using arrow keys to select region
4) when you reach end of region simply hit Alt+w to copy the region
5) now Control+b ] will paste the selection
you can navigate the text using the emacs style navigation key
Control+p, Control+n, Control+f, Control+b etc.
Dan in the comments informs me that if you have vi style key
bindings on then the following applies:
1) enter copy mode using Control+b [
2) navigate to beginning of text, you want to select and hit Space
3) move around using arrow keys to select region
4) when you reach end of region simply hit Enter to copy the region
5) now Control+b ] will paste the selection
To enable vi like cursor movement in copy mode put the following in
your ~/.tmux.conf:
set-window-option -g mode-keys vi
more over what ever you copy, you may dump that out in your terminal
using
tmux show-buffer
and even save to a file(say, foo.txt) using
tmux save-buffer foo.txt
To see all the paste buffers try Control + b #. To dump out the varios
buffers on to the terminal or file you may use
tmux list-buffers
tmux show-buffer -b n
tmux save-buffer -b n foo.txt
