Some  buttons  act  simply  as  momentary  buttons—pressing  one  of  these  causes  an 
action,  but  the  button  does  not  remain  activated,  and  requires  no  deactivation.  
Examples of these are 
Clear
 and 
Undo
. 
Still other buttons act as menus.  When you click them, menus with more buttons and 
function  choices  appear.    Examples  of  these  are  the 
Print
, 
Text
, 
Record
  and 
Animations
 buttons. 
Virtual Keyboard 
The V1’s  virtual keyboard automatically appears whenever the PC’s keyboard would 
normally  be  required.    You  may  use  your  PC’s  keyboard  and  the  virtual  keyboard 
interchangeably. 
There are numerous user interface options, some of which may be helpful to someone 
just learning to use the V1. These are described in the chapter More Options.
