left mouse button again.
The right mouse button has the same function as the keyboard

** PROGRAM SETUP **
The program consists of the following independent parts:
Input system data
Time response
Root loci
Frequency analysis
Close control loop
System Matrix
Display of system - page-overview
Options
Transition from the one independent part to the other independent
part always occurs via the main menu (F10).
The system data are entered through the keyboard or from a data
file. The various program parts use these data and, in general, do
not change them. Data are exchanged when new data are entered or
when data are changed via F6. Old data are automatically saved on a
scratch pad. Five scratch pages are available. When the scratch pad
is full, the oldest data are discarded. All the data on the scratch
pad may be called back and/or reactivated in the menu item
'Display of system - page overview'.
