Characters typed into quick search are interpreted as keyboard shortcut commands

I think this just started with the m4 update on EAC today.

Using Chrome (I know it's not officially supported but I figured I'd note the issue anyway)

1. Click the search input
2. Type 'w'

The manage watchers dialog appears.

Similarly, 't', 'm' and other single-key commands are interpreted the same way.

I have verified that I do not have this issue in Firefox 3.6.8.

I do have the same issue with Safari 5.0.1.
