I just did some tests. With 2.11 pressing the plus key when the text
field has the focus both zooms the map and adds "+" to the field. With
2.12 the map zooms but "+" is not added to the field.

With 2.12 you can reach a behavior that is better than with 2.11. Use
the following:

new OpenLayers.Control.KeyboardDefaults({observeElement: 'map'})]}

and

<div id="map" tabindex="0" style="margin: 0px; width: 100%; height:
250px; border: 1px Solid black;"></div>

(note the tabindex attribute)

With this the map will zoom/dezoom only when the map has the focus.
See the accessible.html example for more information.

I hope this addresses your problems.
