How to change text entry method for searching?

I recall two methods, curosring through an A to Z alphabet "grid" and cell phone style (multiple presses of same number to change character). For the life of me I cannot find this option now. I'm wondering it it changed with new firmware release. 

When I do [MENU], Search, [OK], [Options]

I see, in the upper right corner, Settings and under that ◄√ Keyboard

But for the life of me can't figure out how to change it back to cellphone.

This is on my STB Model 2500. I have not tried this on the DVR (Motorola model).

Thank you in advance for you help.
