Highlighting the words with find function and moving the cursor with coloured cursor movement and displaying the number of found words
Question
I am trying to implement find function to display the words found and moving the cursor over the found words with coloured cursor and highlight the words found and count the number of words found.
I tried highlighter and cursor movement but my highlighter works after the movement of cursor. mainWindow.py

My cursor is highlighted in default and I can not see it properly and I want to highlight it and also looking for creating a function to count the number of words found. I am a learning to develop a text editor and a new programmer and using PyQt5 for GUI.
