Q: 

I need SyntaxDocument supports undo/redo one letter a time.

I mean when I type 'select', it highlights 'select' with blue. When I

press 'Undo', the letter 't' disappears and 'selec' becomes black.

After 3 days googling... I found this but it undoes a block code a time, not a letter: 'http://fifesoft.com/rsyntaxtextarea/TextAreaApplet.php'

This doesn't help. 'http://syntax.jedit.org/'

...and something like that which doesn't help me.

Please give me a hand. I need jar file. :D If there is nothing like that, please give me some advice.

Thank you in advance.
