Photoshop: Brush size shortcuts on Liquify dialog don ́t work with foreign keyboards

I reported this bug during the CS5 beta: When using a foreign keyboard (Spanish), the [ and ] keyboard shortcuts for changing brush size have to be re-mapped, because the [ and ] shortcuts don ́t work on Spanish keybords. After doing that, on the Liquify Filter dialog window, the newly re-mapped shortcuts for brush size don ́t work (the native [ and ] shortcuts don ́t work either). The only way to change brush size is by using the Brush Size slider, which slows down the workflow considerably.
