Is there any way for developers to bind to the undo (ctrl^z) event?

Hello,

It is possible in Author mode but not in Text mode. In Author mode you can set any shortcut for an extension action specified in a document type.

Do you want to change the Undo action in Text mode? What action would you like to run instead of the built-in action for Ctrl-Z?

Hi Sorin,

As you may know, I am working on 'track changes' functionality. The issue I am having is that (for example, with track changes ON) when a user is inserting a change, and then hits ctrl^z, the inserted text is removed, but is now being tagged as deleted!

Normally, I can just stop listening for contentInserted() and contentDeleted() events, but with ctrl^z, I don't get the opportunity to remove my AuthorListener from the AuthorAccess object.

I will try today to handle the ctrl^z event and work around this issue, and i'll keep you posted on the outcome.

Thanks,

Dylan

======================================================
UPDATE:
======================================================
I can handle the ctrl^z event as you suggested, but in doing so, I have completely overridden the original purpose of undo...

What I am *trying* to do is:

1. handle ctrl^z
2. remove the AuthorListener from AuthorAccess
3. turn OFF change tracking
4. let the system perform the undo operation, and
5. turn track changes back ON

Is there a call I can make from within AuthorOperation.doOperation(...) that will perform the undo?

Hi Dylan,

Track changes is work in progress right now... My suggestion would be to wait for that to be available as a standard oXygen feature. The expected time for that to be generally available is the end of April and I hope we will have something that can be tested in a couple of weeks.

In version 10.2 the Author API will allow a custom extension action to call the methods of the undo manager that stores the Author actions for which undo and redo is available.
