Here’s a cool trick I figured out both by digging around in the custom work that our SalesForce consultant did and through some experimentation.
Since every SalesForce object has a unique ID, and since these IDs are used in the URLs for displaying items, it’s actually pretty easy to assemble a link to a page for an item.
I created a custom VisualForce page for our contacts called Contact Card and I wanted a quick way to get to it from the list view. To do so, I created a new custom field (of type formula) for the Contact object, and used the HYPERLINK command. Looking at the address bar in my browser when I was viewing the page for a contact, I was able to determine the syntax to use to assemble a working link. And I discovered that SalesForce supports Unicode characters in its strings, so I was able to find an emoji icon to use for the column so that it would be compact.
HYPERLINK("/apex/ContactCard?id=" + Id, " 📇 ", "_blank")
