Broadcasting typing to all panes:
# To activate:
:setw synchronize-panes on
# To deactivate:
:setw synchronize-panes off
Saving buffer to a file
# Capture the pane. Better give a name to the buffer, to save it later.
capture-pane [-aepPqCJN] [-b buffer-name] [-E end-line] [-S start-line] [-t target-pane] (alias: capturep)
# Save the buffer saved with `capture-pnae` to a file.
save-buffer [-a] [-b buffer-name] path (alias: saveb)
For example:
To capture the whole content of a pane:
capture-pane -b temp-capture-buffer -S -
Then save the buffer to a file
save-buffer -b temp-capture-buffer ~/temp_buffer.txt
And to delete the buffer after saving it
delete-buffer -b capture-buffer
