Re: [netrw] How to use netrw#Call() to create custom mappings

fun! GoUp()
call netrw#Call("NetrwBrowseUpDir", 1)

call GoUp()

function! UserNetrwBrowseUpDir( islocal )
call netrw#Call("NetrwBrowseUpDir", a:islocal)

Hello:

Please try the attached script (goup.vim); it uses netrw#Call with
"NetrwBrowseUpDir". You may need to use
http://www.drchip.org/astronaut/vim/index.html#NETRW 's version of
netrw. There's a problem with that version that I'm trying to address
under Windows, though, so be forewarned.
To use goup.vim:

:e .

which should go up one directory.

The next step: try unbud.vim.

:so unbud.vim
:e .
u

which also should go up one directory.
