# chill-out
## What it does
After N seconds of inactivity (defined as, the user not having navigated
or switched the active tab) display show a page action for that tab.
When the user clicks the page action,
navigate to http://chilloutandwatchsomecatgifs.com/.
"N" is set to 6 seconds in this example. Such a short period is chosen to make
the extension's behavior more obvious, but this is not recommended in real life.
Note that in Chrome, alarms cannot be set for less than a minute. In Chrome:
* if you install this extension "unpacked", you'll see a warning
in the console, but the alarm will still go off after 6 seconds
* if you package the extension and install it, then the alarm will go off after
a minute.
## What it shows
* how to use various `tabs` functions
* how to show/hide a page action
* how to set alarms and handle alarms going off
