KeepFocus doesn't like AutoHide

[honkinberry]

We have a Palette with a textbox, so have discovered that KeepFocus needs to be set for more reliable keyboard entry.
However, if a user has the palette also set to AutoHide, it will never hide.  It seems that KeepFocus is preventing AutoHide completely.
I'd be fine if there was some keyboard command to lose focus like Tab or something, but I can't figure it out.

Anyone have any ideas or suggestions on how KeepFocus and AutoHide can be friends?
