Well it actually takes you to your workspace from inside of CAD. There are a whole host more combinations like this for both your CAD integrations and Vault Explorer to make getting around the interface just that little bit quicker for fans of typing (I'm looking at you AutoCAD users).
Lots of Vault shortcuts follow the standards of Copy (CTRL+C), Paste (CTRL+P) or Open (CTRL+O) but there are plenty of Vault specific time savers such as check in, check out, update properties and manage ownership as well as several you may be hard pressed to anticipate or guess (like the simple combination listed above), so our WikiHelp lays these all out for you on the Keyboard Shortcuts for Vault Commands page here.
Print out a cheat sheet or pick out the most valuable and start to enjoy mouse free interaction with your Vault Add-ins and Explorer.
