The Pause Until action pauses until criteria for conditions are met.

By default (v11.0+) Keyboard Maestro will start to conserve CPU usage of this action if it runs for a long time (after 10 seconds it will conserve a little, after 60 seconds it will conserve a lot) by only checking the condition periodically. You can turn off this feature in the action (gear) ⚙ menu.

Criteria for condition(s)

• Any of the following are true — at least one condition must be true.
• All of the following are true — every condition must be true.
• None of the following are true — no condition is true.
• Not all of the following are true — at least one condition must be false.

Conditions

• Add one or more new conditions by clicking the green + button beside New Condition to select from a list of available conditions.
• Conditions are grouped by the following categories. See the Conditions section for further details.
• After selecting a condition category you can make further choices. For example, if you choose the Application Condition you can choose a specific application to be running, or at the front, and so on.
• Add further conditions by clicking the green + button again.

List of Available Conditions

1. Pause Until the “Finder” app is at front, and the ⌘ key is pressed.

2. Pause Until the Mouse Is Clicked
