+====== For Each Substrings In RegEx Match ======
 The //Substrings In collection// contains the matches in the specified source.
 You can look for matches in the System Clipboard, in a Named Clipboard, in a variable, or in a file.
-You can scan for exact string matches, case insensitive string matches, or regular expression matches.
+You can scan for exact string matches, case insensitive string matches, or regular expression matches, or (v10.0+) for strings separated by exact string matches, case insensitive string matches, or regular expression matches.
-The result, stored in the [[action:For_Each| For Each action ]] variable, can be either the matched string, the position of the match or the range (position,length) of the match.
+The result, stored in the [[action:For_Each| For Each action ]] variable, can be either:
-So, let's assume you've used a variable theRange to store the range in a For Each action.
+* the matched string: the For Each variable is set to the value of the matched string.
+* the position of the match: the For Each variable is set to the position of the match (starting at 1).
+* the range of the match: the For Each variable is set to the range (position,length) of the match.
-It can be referenced by:
+For the range option, the variable contains the position and length with a comma between them, so you can use the normal variable array indexing to access the two numbers, eg if the For Each variable is theRange, then theRange[1] would be the position, and theRange[2] would be the length of the match.
-theRange[1]
+Here's a practical example which superscripts all the numbers in the clipboard.
-theRange[2]
-The range is a comma separated list of values:
+{{ :collection:for_each_apply_style_to_clipboard.png?nolink&510 | Apply Superscript to Numbers in Clipboard }}
-n1,n2
-OR
-Start-of-Match,Length-of-Match
-So the the normal Keyboard Maestro substring notation works with it.
-It's all too easy to get misdirected into thinking the numbers reference match 1, match 2 – but this is not the case.
-Here's a practical example
-{{ :collection:for_each_apply_style_to_clipboard.jpg?nolink |}}
