Keyboard Maestro includes a variety of control flow actions which perform actions depending on a set of conditions.

The condition clause of the flow control actions can be any of:

* 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.

Caution: **If there are no conditions in the set at all, the action will typically not execute anything** except the Until action which will execute the actions once.  **Neither** side of the *If Then Else* will execute.

Generally, a screen image and pixel conditions should be considered a last resort, but there are certain cases where it may be useful – keep in mind that you can use expressions for calculating the location of the pixel too.

When talking about matches, note that “is” refers to equality, “contains” looks for a substring, “matches” uses regular_expression matching, and “conforms” refers to Universal Type Identifier matching (eg public.text).

The available conditions include:

~~NOCACHE~~
<nspages condition -textPages="">
