 What a successful `find` command looks like:

+### Changing the displayed note: `show`
+
+There are 2 ways to use the `show` command:
+1. If an IC_NUMBER is provided, displays the full note of the person with the specified IC_NUMBER on the right.
+2. If no IC_NUMBER is provided, clears the note display on the right.
+
+Format: `show [IC_NUMBER]`
+
+For the first case where an IC_NUMBER is provided:
+* Rules for valid IC_NUMBER are the same as the `find` command.
+* Displays the full note of the person with the specified IC_NUMBER.
+* Does NOT modify the list of persons displayed.
+
+Example:
+* `show T0123456A` updates the note display on the right to show `John Doe`'s note.
+
+For the second case where no IC_NUMBER is provided:
+* Clears the note display on the left.
+* Does NOT modify the list of persons displayed.
+
+Example:
+* `show` clears any note that was being displayed on the right.
+
 ### Deleting a person : `delete`
