Yes. My Priv and Key2 both support it, at least if you mean in terms of scrolling functionality.

Keyboard surfaces that doubles as touchpads aren’t exactly a bleeding edge feature, PS3 chatpad has it and it works on PC(IIRC feels broken until calibrated through secret combo shortcut)

My Blackberry Passport has that and it was super cool and useful. It felt great. I miss that keyboard so much.

Blackberry was innovating but nobody cared; tech media loved to mock them and push them down. They lost a marketing war in addition to a product war.

They went after executives and ended up with the sort that tech people hate. I suspect when everyone started thinking about getting cell phones and asked their tech friend, anything but BB was recommended.

It likely was, depending on timeframe. Others have mentioned the Passport and KeyTwo, and I know my KeyOne supports it. That combination would cover at least 2014 and on.

HP had a phone with a similar feature, based on Windows Phone.
