The Switch or Case action lets you read a string from the System Clipboard, from a Named Clipboard, from a variable, or from a file and then match it against various other strings to choose which set of actions to do.

The action contains a sequence of conditional segments, each of which tests the source string and then conditionally executes the corresponding set of actions.

The condition can test the source and see if:

• has text of some sort.
• does not have text.
• has an image of some sort.
• does not have an image.
• is exactly (case insensitively) a specified string.
• is not exactly (case insensitively) a specified string.
• contains (case insensitively) a specified string.
• does not contain (case insensitively) a specified string.
• matches a specified regular expression.
• does not match a specified regular expression.
• has some flavor that conforms to the specified Uniform Type Identifier.
• does not have a flavor that conforms to the specified Uniform Type Identifier.
• otherwise (aka always).

In all cases at most one sequence will execute, and the conditions are evaluated in order - the first one that matches will execute. So don't put an “otherwise” clause in the middle of your switch statement.
