How to open new window below _all_ other windows?

Question

Suppose my Emacs frame looks like this:

.-------------.
|a     |b     |
|      |      |
|      |      |
|      |------|
|      |c     |
|      |      |
|      |      |
'-------------'

Is is possible now to open another window below all other windows to get the frame that looks like the one below?

.-------------.
|a     |b     |
|      |      |
|      |------|
|      |c     |
|      |      |
|-------------|
|d            |
'-------------'

Yes, it is.

(split-window (frame-root-window) (truncate (* (window-total-height (frame-root-window)) 0.75)) 'below)

The crucial part is (frame-root-window) which returns a window spanning the whole frame.

TIL frame-root-window - thanks! – NickD Sep 02 '20 at 19:15

Maybe `window-total-height` should be called with a WINDOW argument (probably the root window): as it stands, the size is dependent on the currently selected window. – NickD Sep 02 '20 at 19:26
Good call, fixed. – wasamasa Sep 03 '20 at 09:02
