Creating your own expanding functions

You can create your own expanding functions using

transpose-mark-region-start-func

or

transpose-mark-region-end-func

This is how tmr-end--forward-char is defined:

(defun tmr-end--forward-char ()
  "Run transpose-mark-region-end-func with forward-char."
  (interactive)
  (transpose-mark-region-end-func 'forward-char))

Useful info

If you're using Hydra mode you can define a Hydra map to expand / contract the overlay region, e.q.:

(defhydra transpose-mark-end (my-key-map "t")
  "Move transpose-mark-region-end."
  ("f" tmr-end--forward-char "forward-char")
  ("b" tmr-end--backward-char "backward-char")
  ("M-f" tmr-end--forward-word "forward-word")
  ("M-b" tmr-end--backward-word "backward-word")
  ("q" hydra-keyboard-quit "quit" :color blue))

(defhydra transpose-mark-start (my-key-map "r")
  "Move transpose-mark-region-start."
  ("f" tmr-start--forward-char "forward-char")
  ("b" tmr-start--backward-char "backward-char")
  ("M-f" tmr-start--forward-word "forward-word")
  ("M-b" tmr-start--backward-word "backward-word")
  ("q" hydra-keyboard-quit "quit" :color blue))
