Using the mouse in combination with the keys on your keyboard can give you several different advantages and help improve your overall productivity on the computer. Below are just a few examples.
1. Many text editors or programs that allow you to edit text support the ability to quickly highlight all or portions of text by using the Shift key and the mouse. For example, move the cursor to the beginning of the text you wish to highlight, hold down the shift key, and click at the end of the text you wish to highlight. If supported and done properly this will highlight all text in-between the points you clicked.
2. Microsoft Windows Explorer and other file managing programs allow users to select multiple files by holding down the CTRL key and clicking each file or folder they wish to select or hold down the shift key and selecting multiple files at once.
3. Users who visit a website with tables and wish to only select one row of that table can hold down the CTRL key and click and drag on the text in the row they wish to copy.
