-The Execute JavaScript in Safari or Google Chrome action allows you to execute a specified JavaScript, either from a file or text. For example,
+====== Execute JavaScript in Browser ======
-//alert("hello")//
-and return the results. Options for the results of a JavaScript are:
+**The Execute JavaScript Action is available ONLY for [[action:Execute_a_JavaScript_in_Safari|Safari]] and [[action:Execute_a_JavaScript_in_Google_Chrome|Google Chrome]].**
+ * These are actually two separate Actions, one for each browser.
+ * This action allows you to execute a specified JavaScript, either from a file or text entered in the Action itself, and return the results.
+ * If you need to access other Mac apps, see [[action:Execute_a_JavaScript_For_Automation|Execute JavaScript for Automation (JXA) Action]]
+===== Options for Returning Results =====
   *ignore results.

 If the results are to be saved to a variable or a clipboard then further text areas appear in the action allowing you to specify the variable or specific clipboard.
-JavaScript can access variables by using the document.kmvar dictionary, see the Variables section.
+===== Using Keyboard Maestro Variables =====
+JavaScript can only **GET** Keyboard Maestro variables.  They cannot be set:
+```javascript
+var myData = document.kmvar.My_KM_Data
+```
+If your Keyboard Maestro Variable contains spaces, they must be replaced with underscores in the JavaScript.\\
+So, for example:\\
+    Keyboard Maestro Variable Name:  My KM Data
+    JavaScript Reference:            document.kmvar.My_KM_Data
+===== Saving Results to Keyboard Maestro Variables =====
+If you need to set a Keyboard Maestro Variable from the Browser JavaScript, then use a JavaScript return to return the data to the Keyboard Maestro Action, which can be set to save the results as a Keyboard Maestro Variable.
+If you need to set more than one Keyboard Maestro Variable, one approach is to return the data for each variable on a separate line (or with delimiters of your choice), and then parse in a following Keyboard Maestro Search Action using RegEx.
+===== Examples =====
+**1. Return Data for Multiple Variables**
