Android set top boxes rc configure

[tinial]

hi to all of you,

my Android 4.4.2 Tv Set Top Box Q7 Cs918 Full Hd 1080p Rk3188t is working well,but I installed stb emulator 6.0.7 and I have configured my iptv server on it.
When I trie to configure the rc from box to mag250 (add key,ex to change the color of rc app) I can't do it because I can't press OK.

how to save the configuration?

I think you probably need to go into cursor mode, and get the button overlay, then use those to highlight the OK on the screen, then hit OK on the overlay.

I tried different modes but even when I go into cursor mode and move it,all the moves are registered to add key field.....

if anyone has any back up with the remote control mode as mag250 remote control will help me?
