ratpoison provides two commands, fdump and frestore, that allow the user to save and restore frame configurations. Let's say, for example, you have split your desktop into several frames with some windows in these frames and now you want to quickly bring Emacs forward and browse some code (full-screen of course) then return to your funky frame configuration. You could use fdump to dump the frames, hit C-t Q to remove all frames, and then select your emacs window. When you've finished with emacs you could use frestore to restore the windows and frames.
If a frame contained a window when you dumped the frame layout but that window is not present when you restore the layout, the frame holding that window will be blank.
Calling fdump and frestore and copying and pasting the layout by hand each time is a bit cumbersome. There are some simple bindings in doc/sample.ratpoisonrc that allow you to save and restore frame layouts with the press of a key.
Dump the current frame layout as text.
Without an argument the current screen's frames are dumped. With an argument the screen-numth screen is dumped. See Multiple Monitors.
Restore the frame layout based on the list of frames frames. frames should be the text that was printed after calling
Undo the last change of frame layout. This is especially helpful after a only command. One can step at most maxundos steps back in frame layout history.
