#     <c-a>[ Now Enters copy mode
#     Navigate the copy mode with vi-like-key bindings (u for up, d for down, etc.)
#     Hit v to start copying.
#     Press y or Enter to copy the text into the tmux buffer. This automatically cancels copy mode.
#     Paste into the buffer with <prefix>+P (make sure that it’s uppercase P).
#
# Or alternatively, use the mouse to copy text after you’ve entered copy mode.
#
# The above commands use xclip, a Linux command line tool for X11. You can
# replace xclip -se c -i with a platform-specific command like pbcopy (MacOS) or
# wl-copy (Wayland).
