You know that you can move the insertion point in text using your Mac’s arrow keys. But what you may not know is that the Mac offers several shortcuts that let you move around even faster. In most apps, hold down the Option key when using the left/right arrow keys to move left or right by a word. Use Command and the left/right arrow keys to jump to the beginning or end of the current line. Using Option and the up/down arrow keys moves the insertion point to the beginning or end of the current paragraph. And modifying the up/down arrow keys with Command takes you to the top or bottom of the entire document. Even better, add Shift to any of the above to select text from the current point to where you navigate to, so Shift-Option-Up arrow selects all the text from the insertion point to the beginning of the paragraph.
