Suddenly which-key, when triggered, takes up the entire lower half of the screen although only a portion of that is then filled with information. This behaviour started a couple of days ago, but I did not change the behaviour of which-key in any way. 

(use-package which-key
  :ensure t
  :diminish which-key-mode
  :config
  (which-key-mode))

How can I change that?

Sometimes I think that the order in which my config file introduces packages is really crucial in terms of how emacs behaves, is that true?

    "This behaviour started a couple of days ago, but I did not change the behaviour of which-key in any way." -- ok, but what did you change? If you revert those changes, does the problem go away? – phils Feb 24 at 13:06

    "Sometimes I think that the order in which my config file introduces packages is really crucial in terms of how emacs behaves" -- Your init file is a program written in the emacs lisp programming language, so sure, the order in which things occur can absolutely make a difference! – phils Feb 24 at 13:08
  • hard to say. I rewrote my entire configu basically. the minibuffer behaves normally for swiper, find file etc. though... – Carsten D Feb 24 at 13:49

    I suggest you use the recursive bisection technique to figure out what bit of your new config is causing this. – phils Feb 24 at 14:12
  • Does which-key use magit-popup? This recently was replaced by transient inside magit. – InHarmsWay Feb 24 at 15:19

By default which-key uses what it calls side-window that confusingly is below the current window. The variable below controls the portion of the frame the which-key window can take. Check and adjust the value:

;; max height of which-key window, when displayed at top or bottom.
;; valid values: number of lines (integer), or percentage out of current
;; frame's height (float larger than 0 and smaller than 1)
(setq which-key-side-window-max-height 0.25)

  • the initial problem was related to the zoom package, which I use to dynamicallyt adjust buffer sizes when switching between them. Zoom allows to define modes that are disregarded though. Is switch keys minor mode called : which-key-mode? if so it does not work... – Carsten D Feb 25 at 8:28
  • The use of the zoom package (zoom-window?) is crucial information missing in your question. Please update the question. Does which-key work as expected after disabling zoom? The mode is which-key-mode. – Heikki Feb 25 at 12:33
  • it does, I update the question accordingly – Carsten D Feb 25 at 12:34
