问题
Basically looking for a feature similar to Total Commander filter-as-you-type.
回答1:
Isn't the quick search suitable for your need? If i'm not wrong alt+s will show the "quick search" in Midnight Commander but can't check it right now.
回答2:
Hide command line from option menu, alt+s auto show if type any char.
