Shortcuts of the keyboard and of the mouse
  
	A shortcut is a way of doing one thing in a simpler way. 
	For example, if you want to duplicate an object, there is 
	the long waywhich is: 
	first selecting the object, moving your mouse to the copy 
	button then moving your mouse to the position or page where you want to have 
	the duplicate, then move your mouse to the paste or duplicate button. 
	The short way would be to select the object, press CTRL-C, 
	move to the position where you want the object, press CTRL-V. Done in half 
	the time.
	So here the most used keyboard shortcuts
	CTRL C: Copy the selected object
	CTRL V: Paste the previously copied object.
	CTRL S: Save the document (do this as often as you think 
	about)
	CTRL Z: Undo the last action
	CTRL Y: Redo the previous action
	CTRL B: Bold the selected text
	CTRL I: Italic the selected text
	
	Mouse Shortcuts
	The most used would be this one:
	
	CTRL+mouse 
	roller: This will zoom the page while you are rolling your mouse middle 
	button in one direction or the other.
