When my focus in left file display then I click on my right file display up button, this button should works for right file display button only, but this button works for my left file display. same situation for the back and forward button.
my current button code is here
Go UP BACK USEQUALKEYS
Go BACK USEQUALKEYS
Go FORWARD USEQUALKEYS
I wasn't able to reproduce that (trying with the Up button).
But you also do not need
Set STATE=Source in buttons on the file display toolbar. The buttons already automatically apply to the side they are over. Try removing that line and see if things work then, as it shouldn't be needed.
If you want that side to also become the source when using its toolbar buttons, turn on:
- Preferences / File Displays / Border / Set file display to source when border buttons are used
(Alternatively, Click on destination's toolbar only changes state on the same page can be used so the first click just sets the destination side to source and a second click runs the button.)
