I have two text areas on the screen, I have made bold the different words between two text areas and I want to have a button for up and down to go the different words on the text areas. Is this possible ?

    Yes but I suggest you to be a little more precise. Post some code showing what you have tried since now. Your question is still to much vague to get an answer here. – Heisenbug Aug 10 '12 at 10:59

  • yes you are right but I don't know any idea how i can do it, I'm still researching now, can you tell me some kind of method for that. I have found setDefaultButton now but I'm not sure that is not my solution of my problem. @Heisenbug heisenberg ehehe comes up heisenberg from breaking bad sorry im kidding :) – zenx Aug 10 '12 at 11:04

    Seems to me what you need is `modelToView()` and `viewToModel()`, which is inherited by `JTextArea` from `JTextComponent`. Here is one [example](http://stackoverflow.com/a/10309277/1057230) and another [example here](http://stackoverflow.com/a/10463120/1057230), that might can help you – nIcE cOw Aug 10 '12 at 13:04

  • have to look at JTextArea, but notice isn't designated for nice formatting or higlighting, then to use JTextPane instead

  • TextUtilities can help you to find out desired indexes rellative to screen or rellative to the model (Document)

  • can I use keyEvent for that up or down? – zenx Aug 10 '12 at 11:54

    @zenx : `KeyEvent` are not a good option when it comes to Swing. ***[KeyBinding](http://docs.oracle.com/javase/tutorial/uiswing/misc/keybinding.html)*** is what goes with Swing. – nIcE cOw Aug 10 '12 at 13:07
