CCS 6.0 Code Alignment

Hi,

   At CCS 6.0 I can highlight a portion of the code and then press "tab" to shift the code lines to the right. But, how do I shift several code lines to the left? What I am doing is pressing delete key line per line to align the code to the left. Maybe there is a more faster way to do this.

  I am looking at the CCS help how to do this, but I can't find the answer.
