I know that you can go to the Nth % percentage of a file by typing N% in normal mode. Is it possible to advance the line by a given percentage?

To clarify, for an example, can I type something to advance to 10% of the file, then the same thing to advance to 20% and so on?

Sure, you can do it like this:

function! <SID>PercentUp()
    execute 'normal ' . max([line('.') * 100 / line('$') - v:count1 * 10, 0]) . '%'

function! <SID>PercentDown()
    execute 'normal ' . min([line('.') * 100 / line('$') + v:count1 * 10, 100]) . '%'

nnoremap <silent> <leader>- :<C-u>call <SID>PercentUp()<CR>
nnoremap <silent> <leader>+ :<C-u>call <SID>PercentDown()<CR>

With these \- will recede by 10%, while \+ will advance by 10%. The macros accept counters.

  • Nice (+1). - Have you an idea why the macros don't work if in line 1 of the data file?

  • @Janis Apparently the <C-u> didn't work the way I imagined it. Without it the macros work from everywhere (well, hopefully), but they no longer take a count. I'm not sure I understand why though.

  • @Janis I found a version that accepts counters, but it seems unnecessarily complicated. shrug
