Selecting Blocks

The Select function allows you to select a group of blocks so that you can perform a function on the entire selection at once such as freezing blocks.

It also allows you to select blocks based on a particular criterion such as block number or pattern.

The Blocks and Trips options are selected depending on whether you want to select blocks or trips within blocks. The Blocks option is selected by default. The Unblocked Trips check box is activated when you click the Trips option.
