# Saving Window configs in Emacs (in-session)

Sometimes I end up with complex window configs while working in emacs, as you see in the title image. Using Winner mode you can easily track linearly backward through your screens, “undo” style; but sometimes I have a set up–as when developing a system–that I want to return to frequently. It turns out you have Window Registers for this purpose, and they work well.

• window-configuration-to-register: C-x r w <key>

This saves it for easy reloading with C-x r j <key> and you’re back where you want to be!

• jump-to-register: C-x r j <key>
