Description Ivan Furnadjiev CLA 2011-03-01 06:05:37 EST 
With the resolution of bug 337883 we found that it's not possible to close anymore a dialog with ESC key if there is a keybinding defined for ESC key too and the keybinding contextId is org.eclipse.ui.contexts.dialogAndWindow or org.eclipse.ui.contexts.dialog.
Comment 1 Ralf Sternberg CLA 2012-02-17 12:19:31 EST 
This issue exists with all _traversal_ keys: Arrow keys, Tab and Shift-Tab, Return and Escape.

The reason is that for key combinations that are registered as KeyBindings, the default behavior is suppressed using CANCEL_KEYS. But the JavaScript client does not distinguish between traversal and key events.

Since ESC is used to close shells, popup menus, Combo popup lists, cell editors, etc., I doubt that using ESC as a keybinding makes any sense.  The same applies for all other traverse events.  Therefore I would recommend *not to use Escape, Return, Tab, or the arrow keys as keybindings in RAP*.
