emacs movement by thing

movement.el

;; Defines a transient keymap for movement controls and sets up a global key binding to activate this transient map. This transient map, `my-movement-transient-map`, includes bindings for various movement commands like moving forward or backward by a word or character and moving to the next or previous line. The `activate-my-movement-map` function is defined to activate this transient map, and it is globally bound to `C-f`.

;; This setup allows you to press `C-f` followed by one of the specified keys (`f`, `b`, `c`, `l`, `n`, `p`) to perform the corresponding movement operation. The `set-transient-map` call with a second argument of `t` ensures that the transient map stays active until one of its keys is pressed.

;; This is a neat way to create a custom, modal-like interface for movement within Emacs, leveraging your Emacs Lisp skills to tailor your editing environment to your preferences. If you have any specific modifications or additional features you'd like to implement, feel free to ask!
