    Hey,
    Apologies, JavaScript is new to me…
    I am trying to write a macro to toggle a selection or the word where the cursor is between lowercase and uppercase.
    the following code works fine if a text is already selected:

    s = document.selection.Text;
if( s.length == 0 ){s = document.selection.SelectWord();}
n = s.charCodeAt(0);
if( n >= 0x41 && n <= 0x5a ){
	s = s.toLowerCase();
}
else {
	s = s.toUpperCase();
}
document.selection.Text = s;

    But if nothing is selected (and the document.selection.SelectWord() is supposed to kick in) I get the error message:

    ‘s’ is null or not an object at line 3

    Where am I wrong?

    Sorry, got it!
    One has to also load the selection into a variable, so I added s = document.selection.Text; after extending the selection range.
    (Now I have to figure out how to extend the toggle to also capitalize…)
    So, what is the ‘Capitalize’ equivalent to s.toLowerCase?
    And alternatively, how can document.selection.ChangeCase(eeCaseCapitalize); be used?
    Regards

    if(document.selection.IsEmpty){document.selection.SelectWord()}
    document.selection.ChangeCase(eeCaseCapitalize); //Title case

    Thank you Stefan!

    OK, now my first ever JavaScript macro is complete (bug reports are welcomed) :

    
/*
  This eeJavaScript macro will toggle a selected string through the
  sequence of lower case -> capitalize -> uppercase -> lower case again.
  If no string is selected, the word where the cursor is will.
  The starting state is a function of the "first" and "next" characters.
  * If both characters are upper, the string will be converted be lower.
  * If only the first character is upper, the string will be converted
    to upper.
  * If neither the first character nor the next are upper case, the
    string will be capitalyzed.
  A single character will toggle just between lower and upper case.
*/
s = document.selection.Text;
if( document.selection.IsEmpty ){
   document.selection.SelectWord();
   s = document.selection.Text;
    }
f = s.charCodeAt(0);
n = s.charCodeAt(1);

if( (f >= 0x41 && f <= 0x5a && s.length == 1)
                 ||
    (f >= 0x41 && f <= 0x5a && n >= 0x41 && n <= 0x5a)){
    document.selection.ChangeCase(eeCaseLowerCase);
    }
else if( f >= 0x41 && f <= 0x5a ){
    document.selection.ChangeCase(eeCaseUpperCase);
    }
else {
    document.selection.ChangeCase(eeCaseCapitalize);
    }

    Regards,
