Operating a project with an external keyboard  
An external keyboard can be used to operate a project in exactly the same way as with the 
HMI keyboard or screen keyboard. 
 
Note 
The function keys of the external keyboard are disabled.
 
Operating a project with an external mouse  
The project can be operated with an external mouse in exactly the same way as with the 
HMI touch screen. Click the described operating elements with the mouse. 
 
Unintentional reactions to simultaneous operations  
Do not carry out several operations simultaneously. Otherwise, you may trigger 
unintentional reactions.  
•  With touch control: 
Touch only one operating element on the screen at a time. 
•  With key control: 
Do not press more than two function keys at the same time. 
Exception: The keyboard shortcut <CTRL+ALT+DEL> can also be used with the system 
keys. Note that the "Lock Task Switching" option can be activated in the project in the 
Runtime settings of the HMI device.  
Observing the system documentation 
Some operations with the project may require in-depth knowledge about the specific system 
on the part of the operator. If you use jog mode, for example, proceed with care. Refer to 
your system documentation to find any additional information on this topic. 
Operation feedback from operating elements  
The HMI device provides operation feedback as soon as it detects that an operating element 
has been selected. This operation feedback is independent of any communication with the 
controller. Therefore, this operation feedback does not indicate whether the relevant action is 
actually executed or not.
