Another super-lazy one but counting in from the beginning (or end) of a line in order to change something in the "remove & insert" editor can be a bit fiddly when you have to count 20 or 30 characters.

Is there a way of sticking the cursor where you want it & seeing which character that is, or perhaps selecting the section you need to count & seeing how many characters are selected?

Here's an action to take text from the clipboard and to replace the text with the number of characters.

Select some text in a field. Enter command+C. Run the action. Position to where you want the count and enter command+V.

This works really well.
