Deletes matching tags (start and end tags). For example, to delete "<b>" and "</b>" from the following code, place the cursor on either "<b>" or "</b>" and invoke this plugin: <p>Hello, <b>world!</b></p>. Note: This plugin does not validate the markup before matching and optionally deleting tags. Because hand coded markup may contain errors, such as unmatched or missing end tags, it is recommended that the markup is validated before using this plugin to reduce any risk of deleting unmatched tag pairs. Advanced options: set the bPromptBeforeDeleting variable inside the hkp_Main function to 0 to remove the prompts (not recommended).
