How do I temporarily make Weechat's message area "full width" like irssi?

Coming from irssi, I'm used to being able to copy and paste messages from the message view of my terminal (PuTTY) running irssi with relative ease without having hard wraps on the text. This works when irssi is run directly, or when irssi is run in a screen session with the current window set to the size of the terminal (i.e. Ctrl-a, :fit). How do I achieve something similar for weechat? With the default layout, on the right, weechat draws a border and lists the nicks in the channel. On the left, there's a border for the date/time and the message source (the nick, or the event type). Is it possible to temporarily hide all the chrome of the window and present something like what's kept in the logs?
