One of the features Word employs to purportedly make our lives easier is called "smart" selecting. I hate it. I much prefer to select what I want to select without Word presuming I want a whole word or sentence or paragraph. Perhaps you like this feature, but it is not for me.
Under the Advanced tab of Word Options (Figure G), you will see several check boxes regarding selecting. I turn off selecting the entire word, and smart paragraph selection. I also typically click the check box that turns on Use Normal style for bulleted or numbered lists.
