Thanks Sumit for getting back on this ! My scenario is something like this - On pressing Ctrl+z/Ctrl+y, browser performs Undo/Redo in RichTextArea, I want to support this functionality in Buttons, So my intention was rather than capturing onBrowserEvents(EventPreviews) just generate ctrl +z/ctrl+y programmatically on clicking on buttons and let them browser to handle. This will remove javascript quirks too. And I didn't find any undo/redo implemenations in RichTextArea.
