In each state, the current marking is shown first, followed by a list of enabled transitions or steps, depending on the firing strategy:
A transition or step in the given list is selected by entering its number.
transition or step is then executed, and the resulting marking is displayed.
For coloured nets, in addition to the transition number you also have to
specify the firing colour, set apart by a semi-colon. If no transition
is enabled INA returns the message: no transition has concession. In case you
have entered the number of a disabled transition or step, firing is
refused with the message no concession.

Under time allocation, the system time is also shown: transitional period from previous state=2 system time=10.
By entering <cr> , the option to always select and fire the first element of the given firing list is set.
You can repeatedly reverse a firing procedure with <B> , and thus make alternative selections.
With this command, the initial state is restored, which allows to investigate a different path through the reachability graph. At the end of firing, you do not need to use this function, since it is automatically applied.
