Palming the keys is as it sounds - your palms literally touch the keys (or stay very close to them) when playing.
First you go for the most extreme version: hold an easy interval (say, as sixth) on the black keys while allowing your palm to mash down the white keys. This gives you the sensation of being in a state of rest even whilst holding an interval or chord. The next thing that Alan had me do was to use the grasping of my fingers to raise and lower the second MCP joint slowly - first so little that the palm doesn't leave the keys, then eventually enough so that the palm is lifted. I find my shoulders re-arrange themselves when I do this.
Also, if you haven't looked at it already, I suggest you check out chapter 19, The Thumb in Arpeggios, in All Thumbs. It deals with the location (or perhaps better put, movement) of the wrist when the thumb goes under.
