S S, If the settings tiddler is named in the edit text widget it will be created when the person enters the separator character. Perhaps you can then test the length of the field and if its greater than one display "sorry one character only" and the 1st character. This way you do not need a button, the edit text field creates the tiddler/field, then for safety you could design your macro to only use the first.
