Similar to org mode, for taking colorful notes in Emacs, I would like to define some special characters (used in the beginning of the lines) to tell Emacs which colors (foreground/background) should be used for highlighting the entire current line. Is there any script for this purpose? If yes, please let me know how I can use it.
An example of the notes :
# list of operating systems : << highlighted with red @ Unix << highlighted with blue @ Linux << highlighted with blue @ Minix << highlighted with blue
