 ===== How to Get Keyboard Maestro Variables =====
+Keyboard Maestro sets the environment variables for the script to include all your variables, using a prefix of `KMVAR_` and your variable name with spaces changed in to underscores (‗). For example, your Keyboard Maestro “File Name” variable will be available as the environment variable `KMVAR_File_Name`.
+By default, all variables are included, but you can select No Variables, or specific variables as desired using the popup menu next to the script (v11.0+).
 Swift scripts can get (but not set) Keyboard Maestro Variables by using environment variables, for example:
@@ Line 40: / Line 44: @@
 let myString = "the Value"
-NSAppleScript(source: "tell application \"Keyboard Maestro Engine\" to setvariable \"fromSwift\" to \"\(myString)\"")?
+NSAppleScript(source: "tell application \"Keyboard Maestro Engine\" to setvariable \"fromSwift\" to \"\(myString)\"")?.executeAndReturnError(nil)
-.executeAndReturnError(nil)
 </code>
 Note that if the value might contain backslashes or quotes, you will need to deal with quoting them, replacing every backslash with backslash-backslash, and every double quote with backslash-double quote.
