Another most powerful thing about Jwno's key binding system is that, it has an internal stack for keymaps. Only the top keymap in the stack takes effect, and we call it the transient keymap. You can use the special commands :push-keymap and :pop-keymap to manipulate the stack. The commands are special because they operate directly in the UI thread, and you can't use the :call-command method from the command manager to call them.
For example, we can define a simple transient keymap only for moving windows around:
(def yank-mode-keymap
(let [keymap (:new-keymap (in jwno/context :key-manager))]
(:define-key keymap "Down" [:move-window :down])
(:define-key keymap "Up" [:move-window :up])
(:define-key keymap "Left" [:move-window :left])
(:define-key keymap "Right" [:move-window :right])
(:define-key keymap "Esc" :pop-keymap)
keymap))And then enable it when we press Win + K:
(:define-key root-keymap "Win + K" [:push-keymap yank-mode-keymap]
"Yank mode")When yank-mode-keymap is in effect, you can use the arrow keys without any modifier keys to move your windows. The keymap will remain in effect until you press the Esc key, which calls the :pop-keymap command.
