Transient State menus
Transient state menus make it simple to run commands multiple times, using a single key press, from a specific sub-set of commands.
For example, Font Scaling transient state menu allows you to repeatedly increase the size of the buffer font just by using the + key. The Font Scaling transient state menu contains the sub-set of commands related to scaling, so you can decrease the font size just with the - key and reset the font with 0.
Transient-states are usually triggered by using a keybinding with the following pattern: <Leader> <group> . where group is the category the transient-state falls under.
When in a transient-state you will see documentation at the bottom of your window. To exit a transient-state press q.

Hydra menus
Spacemacs uses hydra to create these transient states. Some packages also include their own Hydra menus. An example of this is the Clojure refactor hyrda menu.
C-c C-f h h- clj-refactor (hydra menu)
Propose transient state keybinding for Clojure layer - cljr-refactor
hydra-cljr-help-menu/body is an interactive compiled Lisp function in `clj-refactor.el'.
(hydra-cljr-help-menu/body)
For more information check the manuals.
Call the body in the "hydra-cljr-help-menu" hydra.
The heads for the associated hydra are:
"n": ‘hydra-cljr-ns-menu/body’, "c": ‘hydra-cljr-code-menu/body’, "p": ‘hydra-cljr-project-menu/body’, "t": ‘hydra-cljr-toplevel-form-menu/body’, "s": ‘hydra-cljr-cljr-menu/body’, "q": ‘nil’
The body can be accessed via ‘hydra-cljr-help-menu/body’. ```
