from Npp import editor
"""
MultiEdit
acts based on the position of the cursor, NOT on selection
- if cursor is located before the word it will prepend new text
- if cursor is within a word it will overwrite the words and
- if cursor is at the end of a word if will append new text
Usage:
every run will activate the multi_edit function,
in order to stop it, cancelling the selection would be needed - aka use arrow keys
