Can I create "BACK" on the touchscreen instead of the FN (left top) key ?

or can the 5D button left could be program as "BACK" ?
  Thanks

Hi, thanks for the inquiry. We're sorry that we couldn't create a back on the touchscreen and this back function can't be selected using the 5D button. Please refer to the image below for you to check the options that you could use using the 5D button. Thank you for understanding.

This is so SAD... you can just put an ARROW LEFT ... on the display.  The PHYSICAL BACK button is now very sluggish....  ;(

Why would you want to though?

For us the fact you have the equivalent of a forwards and back button dedicated to that task at the top of the controller is common sense.

It’s the same as forwards and back on any browser, so it’s pretty logical.
