This article is just to reduce the step for publishing an item, currently if we have to publish an item in content tree where the editor is, we have to navigate to publish section in the ribbon and then click publish item.
How easy the item publishing will be if the user has an option to publish the item by Right clicking of selected item.
I would like this as a wish to feature with upcoming Sitecore default setup.
To get this option you have to create a context menu item named “Publish Item” in core database in Context Menues section (“/sitecore/content/Applications/Content Editor/Context Menues/Default”) of the template type Menu Item ( ”/sitecore/templates/System/Menus/Menu item”) and add desired Display Name, Icon and the message item:publish(id=$Target) and finally save it.
Switch to master database you will able see context menu “Publish item” from where you can perform publishing.
