Question

p.e. I have a block of text selected (using Ctrl-V) and want to extend it in a vimscript to a new location p.e. 30 lines below

Does anyone know how to do this?

Answer 1

You can use the markers '< and '> to move to the beginning and end respectively of the most recent visual selection. So a simple function such as

EDITED to use gv and a jump variable.

function! ExtendVisual(jump)
    execute "normal! gv" . a:jump . "j"
endfunction

vnoremap <silent> <leader>e :call ExtendVisual(30)<CR>

will let you extend the current visual:q region by 30 lines using \e.
