quick shortcut question

How do I select a part of a list
For example if I have the numbers 1 through 99 in a vertical list (such a list of podcast episodes), how can I easily select number 70-90 without having to individually select all of them while holding down the Command key?
EDIT Never mind, I figured it out

could you tell me how, because i don't know how

To select beginning to end:
1) select the first one you want to select
2) hold shift and select the last one you want to select
*everything in the middle of the two will also be selected

To select individual files:
1) hold command and select all the files you wish to select

If you are in list view, clicking and dragging *outside* of a filename will also select files...
