-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.
+{{:action:switch-icon.png?nolink|}}
+====== Switch or Case Action ======
-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 //Switch or Case action// is used to perform different actions based on different values of a common _parameter_.**  It is very similar to the [[https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/switch|JavaScript Switch]] statement.

+The _Switch_ Action is a good alternative to using multiple, nested, [[action:If_Then_Else|If/Then]] Actions.
+----
+===== Parameters =====
+**The Switch _parameter_ may be any of the following:**
+  * [[:Clipboards|System Clipboard]]
+  * [[:Clipboards#Named_Clipboards|Named Clipboard]]
+  * [[:Variables|Keyboard Maestro Variable]]
+  * Text (which can use [[:Tokens|Tokens]])
+----
+===== Default Configuration =====
+When you insert the _Switch_ Action, it is configured to switch based on the _System Clipboard_, but can be easily changed to other parameters.  It initially looks like this:
+{{:action:km-7.3-switch.png?nolink|}}
+For each _Condition_ that you add, you can enter zero or more _Actions_ that will be executed when that _Condition_ is met.  After those _Action(s)_ are executed, or if no _Conditions_ are met, the _Switch_ Action is exited.
+----
+===== Conditions =====
+The _Condition_ can be and of the following:
 * has text of some sort.

 * is exactly (case insensitively) a specified string.
 * is not exactly (case insensitively) a specified string.
+* is alphabetically before a specified string. (v7.2+)

 * contains (case insensitively) a specified string.

 * 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.
+The _Otherwise_ _Condition_ will execute if none of the above _Conditions_ are met.  The _Switch_ Action will then exit.  So, the _Otherwise_ _Condition_ should always be placed as the last _Condition_ in the _Switch_ Action.
