I love my Planck EZ keyboard. Today I had to do a lot of numerical data entry, and realized that having a dedicated numerical input pad could be helpful. 5 minutes later I had edited the layout of the keyboard. It now has a new layer that holds a numerical entry pad with digits, operators and decimal separators. With the new macro system in the configuration software I could even make keys for 00 and 000. The keys are colour coded to help me remember the positions.
