Example of the fpw_read_more_text filter in Feature a Page Widget 2.0. The widget uses an accessible "read more" link that says in full "Read More about {Page Title}..." to screen readers, search engines, etc. but only appears as "Read More..." The filter only modifies the visible portion of the link.

fpw_read_more_text_filter_examples.php

<?php
/**
 * modify the "Read More" text in the accessible "Read More" link
 * 
 * example: change it to "Continue Reading"
 * 
 * @param	$read_more_text		string		The "________" in "________ about {Page Title}"
 */
function fpw_change_read_more( $read_more_text ) {
	$read_more_text = __( 'Continue Reading', 'your-text-domain' );
	return $read_more_text;
}
add_filter( 'fpw_read_more_text', 'fpw_change_read_more' );

Hi,

I found your plugin and I really like it! But I need to change the Read More text but somehow I can't figure out how to.

I added your above snippet to my functions.php file but I don't know what you mean with "your-text-domain". Do I change this string with my website domain?

Best Regards
