What happened to the left arrow key?

This is a Great calculator. I thought that the left arrow key had been replaced by the CLX key, but I found out that there are options to set the behavior of the key. Everything is great again!!

What happened to the left arrow key?

I loved the first version of this calculator! Then when I upgraded, I lost the left arrow key so my only option when I miskey a number is to hit CLX and reenter the whole number - what a pain in large numbers!!! Why was the left
 Arrow removed!! Bring it back!!!! I hate the CLx key.

Great app - issue with Logitech MX Keyboard

This is a great app. Wish it stayed free like others.
The ENTER key on Logitech MX Keyboard doesn't work. Have to use the Return key to enter values.
