Left shift (Opposite to shift) to align code

[SasStatistics]

When writing code in SAS, I can select a part of the code and then press SHIFT (EDIT) TAB. This will move my code to the right. 

Is there any command that will do the same thing but move my code to the left, i.e. a "Left Shift"? 

Edit: I am using SAS Enteprise Guide.

What SAS user interface/platform are you using?

Enterprise Guide. (I edited post above, should say TAB, not SHIFT.).  Sorry for typo and as always, thanks for the reply.

When text is selected, TAB will shift to the right, while SHIFT-TAB will shift it to the left.
