What is a Dynamic Activity in a Pathfinder?
A Dynamic Activity is an already created activity that you choose an icon or an icon sequence to represent.
Once you make an activity dynamic, you can be in any other activity, activate the icon you selected for your dynamic activity, speak a message from it and return automatically to the original activity.
Let's say you have a "Cookies" Activity and you want to make it dynamic.
You make an activity dynamic by selecting the Dynamic Activities option in the ACTIVITY menu and then by selecting an icon to represent the activity.
To Make an Activity Dynamic:
1. Go to the Toolbox and open the ACTIVITY menu.
2. Activate the Dynamic Activities option.

3. Make sure that the Dynamic Activities option is set to On.
4. Make sure the Activity Persistence option is set to Temporary.
Temporary means that the activity will stay dynamic for one activation only, then take you back to where you were.
If you want to remain in the new activity and not return to your original one, set this option to Permanent.
NOTE: Regular activities cannot be set to Permanent or Temporary unless they are made Dynamic first. Only Dynamic Activities can be Permanent or Temporary.
5. Activate the Add Dynamic Activity option.

6. Select a sequence (a one-icon sequence is quickest) that will remind you of the activity.
For example, for the "Cookies" activity you might select the KITCHEN icon which is the pan with a thermometer
in it.
7. Activate OK when you are finished.
NOTE: You will not mask any vocabulary when you select a sequence for an activity.

8. Now activate the activity you want to make dynamic (e.g.,"Cookies"). You may have to activate More Items before you see the activity you want.
9. Activate OK. Activate OK again to exit the menu.
To Test the Dynamic Activity:
Activate the KITCHEN icon in your core vocabulary area.
The "Cookies" activity opens on your display.
Activate an icon in the activity.
The message is spoken and you return to your original activity.
TIP:
Since a Dynamic Activity is intended to be selected from an icon or an icon sequence, you may not want to see a Dynamic Activity listed in your standard activity row.
Use the Hide Activity option in the ACTIVITY menu to keep a Dynamic Activity from being visible in the standard activity row.
