The workflow of Shutter is a simple 3-step process:
- Add events that are to be monitored, and
- Add actions that are to be executed when the specified events occur.
- Start monitoring for the specified events.
The details are as follows:
Step 1: Load Events
Events are usually based on periodic checking of a system state, execution state of a process, or system time.
- You can add multiple events, and also set the logical relationship between them.
Note that this step only loads the events; Shutter will not start monitoring for the event till you press the 
button (see Step 3).
Step 2: Load Actions
Actions are executed one by one, from top to bottom.
You can add as many actions as you want, but please be aware of the following factors:
- Each action can affect the execution of the other actions listed below it.
To avoid that, you may have to change the order of the Actions by moving them up/down. - Some of these actions are terminal: They close Shutter, log out the Windows user or shut down the PC. For example: the Shutdown action.
Therefore, such Actions must be placed at the very end of the Actions stack. Otherwise the actions listed below them will never be executed!
Step 3: Start monitoring
Press the button. Shutter starts monitoring for the events. The button changes to 
. Press it if you want to stop Shutter in an emergency.
- Shutter also has a
button, which starts all actions without waiting for triggering the event-set.
- This is useful to check how the specified actions would actually work.
