-Edit Last Entered Work Notes/Additional comments
+# ✏️ Edit Last Work Notes or Comments via Modal (Client UI Action)
 
-This UI action is built specifically to edit the last entered work notes/ additional comments by the user in incident form or it can modified for any table which support this journal fields.
+## 📁 Location  
+**Category:** `Client-Side Components`  
+**Subcategory:** `UI Actions`  
+**Snippet Folder:** `Edit Last Comments Modal`
 
-There is some restriction around journal fields/ work notes as user cannot edit or adjust the work notes/additional comments that they entered. If they wish to edit it, I have introduced a new
-UI action which calls the UI pages which will automatically populates the last entered work notes/comments and user can adjust and submit it.
+---
+
+## 📌 Description
+
+This client-side function enables inline editing of the **most recent Work Notes or Additional Comments** on an Incident record via a modal dialog—without navigating away from the form.
+
+When triggered from a **UI Action**, it opens a modal powered by the **UI Macro** `edit_worknotes_comments_inc`, passing the current record’s `sys_id` to enable dynamic data loading and editing.
+
+---
+
+## 🚀 Features
+
+- 🪟 Opens a modal dialog using `GlideModal`
+- ✏️ Allows quick editing of the latest Work Notes or Additional Comments
+- 🔄 Passes the current Incident `sys_id` to the UI macro using `setPreference()`
+- 🎨 Sets modal width and title for a better user experience
+- 🧩 Seamlessly integrates into the form via a client-side UI Action
+
+---
+
+## 🧪 Example Use Case
+
+Imagine a fulfiller needs to quickly revise their most recent comment on a ticket. Instead of scrolling through activity logs or editing the full record, they simply:
+
+1. Click the **“Edit Last Comment”** button on the form.
+2. A modal opens, pre-populated with the last comment.
+3. They update and save — without navigating away from the current form.
+

+

+function openEditLastCommentModal() {
+    var dialog = new GlideModal("edit_worknotes_comments_inc");
+    dialog.setTitle("Edit Last WorkNotes/Additional Comments");

+    dialog.setWidth(550);
