No, nothing strange really

...
I want to have MN functionality as it is now, meaning REV & FWD by MN, PREV & NEXT also by MN.
Above that, I also want original REV & FWD functionality (with visible frames x2...x4...x8...x16) by LEFT & RIGHT arrow buttons since I never use chapter browsing.
But if you find it impossible to make it configurable, nevermind... I'll live without it.
I just tried mp3 navigation, nice work again.
