Keyboard shortcut to "untab" (move a block of code to the left) in eclipse / aptana?

In Visual Studio and most other half decent IDEs you can simply do SHIFT+TAB. It does the opposite of just TAB.

I would think and hope that the IDEs you mention support this as well.

Shift-tab outdents again :)

Here is a general answer for untab :-

In Python IDLE :- Ctrl + [

In elipse :- Shitft + Tab

In Visual Studio :- Shift+ Tab
