alarm hasn't been documented because it is not working in all cases.
Here is an example of code that shows how it is supposed to work:
=======================cut here==============================
alarm -r tbar +10
tbar.alarm()
{
printf $'\E]0;%T %s\a' now "$PWD"
}
=======================cut here==============================
This code sets an alarm that goes off every 10 seconds. By defining
an alarm variable with alarm, you can specify a callback function var.alarm
that will execute when the alarm expires.
In this case the title bar is updated with the current time and the
current working directory every 10 seconds.
