Here are some not-so-well-known keyboard shortcuts in Word:

• Rather than pecking at the Delete or Backspace keys to delete a word, place your cursor at the end of the word then press CTRL+Backspace
• Double-click a word to highlight it
• Triple-click to highlight an entire sentence
• Highlight a word and press SHIFT+F3 to toggle through capitalization options
• CTRL+G to go to a specific page number
