Hi,

Is there anyone that know how to bind a key that "exec" six terminal windows. I manage to figure out how to do this, but all windows was on one row.  What I would like to have is that 3 on top and 3 on bottom.

Like this,

|    T1    |     T2   |      T3   |
| _ _ _ _ | _ _ _ _ | _ _ _ _ |
|            |            |            |
|    T4    |     T5   |      T6   |
| _ _ _ _ | _ _ _ _ | _ _ _ _ |

Thanks in advance !
