As long as you don't specify the autostart="true" param, it just does the
"useful" timeout when triggered from a user-action (button press).
Note that even without using autostart, you can still create "tail end"
timer loops that can then be controlled by setting a flag field.
For example, here's how I implemented the timer's "elapsed time" display:
\define ticker_actions()
<$action-timeout delay="1000" id="$(currentTiddler)$" actions="""
<$list filter="[[$(currentTiddler)$]is[tiddler]]">
<$action-setfield $timestamp="no" now=<<now YYYY0MM0DD0hh0mm0ss0XXX>>
/>
<$reveal default={{!!stop}} type="match" text="">
<$importvariables filter="TiddlyTools/Timer"> <<ticker_actions>>
</$importvariables>
</$reveal>
</$list>
""" />
\end
Note how the timeout widget invokes an action that sets the "now" field (to
track the current time...
used to calculate the elapsed time) and then it checks if the "stop" field
is blank. If it is, then it
schedules another timeout to occur in one second. This function will keep
invoking itself once
a second until "stop" is set to a non-blank value (i.e., "true"), which is
triggered by the user
when they explicitly press the "stop" button in the timer interface.
