I am new to gvim. Now I am trying to use keyboard to simply go through/search the file and folders with minimal up(k) and down(j) operation, I try vim documentation but not quite understand the symbols
Any help is appreciated
You might want to try netrw+gvim. In the menu for [Netrw]:[Explore] are four searches:
(see :help netrw-starstar). Use :Nexplore and :Pexplore (or shift-down, shift-up mouse) to go to the next/previous file on the resulting search list, and use a [return] to enter the file.
For example: * :Explore **//xfile
