Navigating with the Mouse and Keyboard
The most common way to navigate text is with the mouse and navigation keys:
Use the LEFT ARROW and RIGHT ARROW keys to move one character at a time or in combination with the CTRL key to move one word at a time. The UP ARROW and DOWN ARROW keys move one line at a time.
Click a location to place the cursor there.
Use the scroll bars or scroll wheel on the mouse to move through the text.
Use the HOME, END, PAGE UP, and PAGE DOWN keys to move through the text.
Use CTRL+PAGE UP and CTRL+PAGE DOWN to move the insertion point to the top or bottom of the window, respectively.
Use CTRL+UP ARROW and CTRL+DOWN ARROW to scroll the view without moving the insertion point.
