Open Files dialog does not appear under IDEA 12

[cbeams]

Greetings,

I'm trying out TabSwitch for the first time under IDEA 12.0 Ultimate, and am unable to get the Open Files dialog to appear.

Per the description at http://plugins.intellij.net/plugin/?id=179, this behavior should be mapped by default to Alt-A—this was not the case, i.e. I had to set up the shortcut myself in Settings->keymap.

And once I had set up the mapping, the Open Files dialog does not appear as expected—the behavior instead is that I jump immediately to the most recently open editor. Successive presses of Alt-A continue toggling back and forth between the two most recently open editors.
