Daniel Hutmacher previews a table with a keyboard shortcut:
On the surface, these query shortcuts are just what the name implies – a key combination that you can press to run a command or execute a stored procedure. But there’s a hidden super power: whatever text you’ve selected in SSMS when you press the keyboard combination gets appended to the shortcut statement.
That is quite useful, though I’ve already bound all of those SSMS shortcuts to various forms of WhoIsActive.
