How it works:
<ol>
<li>
Click ‘Tools > Bulk Term Editor’.
</li>
<li>
Select a taxonomy. 
If you selected a taxonomy which has terms, it will read those into the field.
</li>
<li>
Get your data ready. 
Prepare your data by spreadsheet such as Excel. 
If you selected a taxonomy which has terms at the step 2, it’s easy to copy that data into the spreadsheet.
</li>
<li>
Copy the cells. 
You may copy all lines, but the more lines there are, the more times spends. 
Copying the minimum necessary lines is the best, but safer to copy all lines.
</li>
<li>
Paste to this plugin. 
Paste it into the ‘Term’ field of this plugin.
</li>
<li>
Execute. 
Clicking the ‘Edit’ button executes it.
</li>
</ol>
<h4>Delete</h4>
Entering a ‘*’ in beginning of line will delete.
<h4>Change the term slug</h4>
Entering a ‘>New slug’ after the term slug will change the term slug.
<h4>Add</h4>
When the term slug is a blank or new, add.

Just came here to say THANK YOU, this plugin is a very very handy and useful tool to manage BIG list of taxonomies. Thank you. 

Awesome Job! Thanks

You can register or edit terms in bulk. Copy cells in the spreadsheet, all that remains is to paste to this plugin.

Up until now the way theme and plugin developers find where to hook into with their add_action() and add_filter() functions is either to search through the WordPress code base, or find find a reference to the hook in the codex.
What Simply Show Hooks does is give you a simpler way to see these hooks by displaying them in-line on the page that you are on. All that’s left to do then is copy the hook you need, and paste it in to your add_action and add_filter functions like this: 
add_action( ‘wp_enqueue_scripts’, ‘my_enqueue_scripts_action’ ); 
add_filter( ‘the_title’, ‘my_the_title_filter’ );
I made this plugin so I could find WordPress hooks quicker and I use it all the time, so I thought I’d share it and see if it could help others.
Enjoy!
Please note that in odd cases, due to the nature of actions and filters, the plugin may display a hook in place that disrupts the display of your site – in which case we always display the ‘Hide Hooks’ button so you can switch it back off. This won’t disrupt the look of you site to anyone but you so don’t worry.

Simply Show Hooks

Good

Simply Show Hooks helps theme and plugin developers to quickly see where all the action and filter hooks are on any WordPress page.
