When selecting or unselecting checkboxes in a checkbox list, there are a few short cuts you can take to help you work even faster.
1.
To select all checkboxes in a list, right-click any of the checkboxes twice.
2.
If there is a series of check boxes in a list and you have checked more than one box, you can simultaneously uncheck all of them and select just one by right-clicking on the desired checkbox.
3.
If you want to select several checkboxes in a row, click on the top-most checkbox, hold down the Shift key, and click on the bottom-most checkbox. All the checkboxes in between will be selected.
