Explanation
- Set up the clipboard.
- Check if insert key is pressed.
- Check if there's any text in the clipboard.
- Get the text from the clipboard.
- Remove all the html tags.
- Insert the text at the cursor position.
Note
Note that you can still press Ctrl-V to paste the text. The difference is that Ctrl-V will paste the tags as it is, i.e. with all the html tags. However, if you use the Insert key, the html tags will be removed.
