3.4 Using Keys 
The monitor has three types of keys:   
  Softkey: A softkey is a graphic key on the screen, giving you fast access to certain 
menus or functions. The monitor has two types of softkeys:   
  Parameter keys: Each parameter area or waveform area can be seen as a softkey. 
You can enter a parameter setup menu by selecting its corresponding parameter 
area or waveform area. 
  QuickKeys: QuickKeys are configurable graphical keys, located at the bottom of 
the main screen. For details, refer to the section 2.6 QuickKeys. 
  Hardkeys: A hardkey is a physical key on a monitoring device, such as the main menu 
hardkey on the monitor’s front. 
  Pop-Up Keys: Pop-up keys are task-related keys that appear automatically on the 
monitor screen when required. For example, the confirm pop-up key appears only when 
you need to confirm a change.
