Repetition Counter: Determine here how often the keyboard action is supposed to be repeated. If you need for example three tab steps in order to change onto another dialog element of the target application then you can do that in one action.
System Keys: Select one of the system buttons in the middle selection field if they need these for the keyboard action.
Shift = Shift-key
Ctrl = Strg-key
+ Key: Declare a key in the right selection field for the keyboard action or select one of the predefined special keys.
Some predefined keys:
Wait_100_ms = A delay of 100 ms is inserted (If the previous keyboard action needs time for processing). With the repetition counter also longer times can be defined.
Backspace = Key above the return key
Menu = left of the right Ctrl key;
