How to trace shortcode to its functionality

What I always do is, I search the files…

So I use the “Search in files”-function in Notepad++ (which I am using) and limit the search to the directory, where I think, I will find what I am looking for.

So, probably, you know already the plugins directory. You enter this information into the folder input line e.g.:

c:/xampp/htdocs/wordpress/wp-content/plugins/plugin-with-sortcode/

When I am looking for a function I search

function NameOfFunction(

Shouldn’t I find it, I try sometimes without the function part.

You are searching for a shortcode, you could try things like

add_shortcode( 'nameOfshortcode'
add_shortcode('nameOfshortcode'
add_shortcode( "nameOfshortcode"

You see, I alter the quotation marks as well as the spaces. If the first doesn’t work maybe the second or the third spelling.

Hope this helps.
