(*) You can define your own timer ID by replacing the XXX with other ASCII characters.

(**) Timers may be qualified in one of following ways:

 

1.as start or end timers, by replacing the "x" character with a lower case ASCII letter "s" for a start timer or a lower case ASCII letter "e" for an end timer; for example, the timer identification AUDs designates the start of audio following silence, while AUDe designates the end of the audio segment.
2.as enumerated timers, by replacing the "x" character with an ASCII numeric character; for example, SEC1 may be designated secondary timer number 1, SEC2 may be secondary number 2, and so on
3.as multiple timers, by having multiple instances of the same timer ID; one may have, for example, multiple instances of MRK. Custom timers belong in this category.
