What do you hold down to select a sentence?

This is a bit tricky to answer because it depends on what you're using to select the sentence:

* If you're using a mouse: You would click and drag the mouse over the sentence you want to select.

* If you're using a keyboard: You would hold down Shift while using the arrow keys to highlight the beginning and end of the sentence.

* If you're using a touchscreen: You can usually tap and drag to highlight the sentence.
