Vim is a text editor based off the classic vi editor. It is different from other text editors in that it has different modes of operation. You can learn about vim through various websites.
Vim is a very capable editor for mobile devices because of its low footprint and efficiency of key strokes.
Configuration
Vim can be configured through the ~/.vimrc file. Here are some items that make it easier to use vim on the N900.
" Map the comma key to colon map , : " Press jj while in insert mode to press escape inoremap jj <esc> " CTRL+Up to page up, CTRL+Down to page down map <c-up> <c-u> map <c-down> <c-d> " Use 256 colors set t_Co=256
Finger scrolling
Add the following to your ~/.vimrc to enable scrolling by dragging the screen.
" Drag scrolling. Taken from the ez_scroll vim script
" http://www.vim.org/scripts/script.php?script_id=3141
func! MScroll()
let l:done=0
let l:n = -1
let l:w0 = line("w0")
let l:last = line("$")
while done!=1
let l:g = getchar()
if l:g != "\<LeftDrag>"
let done = 1
else
if l:n == -1
let l:n = v:mouse_lnum
let l:fln = v:mouse_lnum
else
let l:new = l:w0 - v:mouse_lnum + l:n
if l:new<1
let l:new = 1
endif
let l:diff = -v:mouse_lnum + l:n
let l:nd = line("w$")
if l:nd+l:diff>l:last
let l:new = l:last - winheight(0) + 1
if l:new<1
let l:new = 1
endif
end
let l:wn = "normal ".string(l:new)."zt"
if (l:n != v:mouse_lnum)
exec(l:wn)
redraw
endif
let l:w0 = line("w0")
let l:n = v:mouse_lnum + l:diff
endif
endif
endwhile
:call cursor(v:mouse_lnum,v:mouse_col)
endfunc
:set mouse=a
