Using keyboard shortcuts can greatly increase your productivity, reduce repetitive strain, and help keep you focused. For example, highlighting text with the keyboard and pressing Ctrl + C is much faster than taking your hand from the keyboard, highlighting the text using the mouse, clicking copy from the file menu, and then putting your hand back in place on the keyboard. Here are a few, quick useful shortcuts.
Ctrl + C Copy the highlightedtext or selected item; Ctrl + V Paste the text or object that’s in the clipboard; Ctrl + P Print the page being viewed – i.e. your document in Microsoft Word or the web page in your Internet browser.
