Executing a Query in SQL Server Management Studio

Is there no single keyboard shortcut that I can always use to execute a query in SQL Server Management Studio?

In the most common scenario, when I've got a table open and I want to write a quick query in the "SQL Pane," the keyboard shortcut is Ctrl+R.  But in the less common scenario where I start by clicking the "New Query" button on the toolbar, the keyboard shortcut to execute the query is F5.

Why are there two separate keyboard shortcuts I have to memorize to do the exact same action?
