That will be a matrix template. To do a simple vector, just press SHIFT-5. Press the [,] key to move to the next item. Note that if you accidentally made a matrix and the cursor is inside the matrix and there is no more then 1 row), just press SHIFT-5 and it will toggle it back to a vector.

proot([1,2,-25,-26,120]) --> [-5.,-3.,2.,4.]

Toolbox->CAS (button on the bottom of the screen)->Polynomial->Find Roots
