I was once forced to use a windows development suite called "Centura". The only good thing i remember was its swap current_line with upper/lower line. function! MySwapUp() let cur_col = virtcol(".") normal ddkkp execute "normal " . cur_col . "|" endfunction function! MySwapDown() let cur_col = virtcol(".") normal ddp execute "normal " . cur_col . "|" endfunction " swap lines and preserve cursorx " todo: in visual mode, perform swap with line before/after the selection noremap <S-Up> :call MySwapUp()<CR> noremap <S-Down> :call MySwapDown()<CR>

Instead of "ddkkp", how about simply "ddkP"? One less keystroke! :) (Saving keystrokes is one of the biggest reasons why people use vi-like editors in the first place.)

Forgot to mention this, but it might be better to make the mappings <silent> so the effects can't be seen on the command-line. Also, swapping up when the cursor is on the first line doesn't appear to be quite what is desired (or the first TWO lines if the ddkkp format is used instead of ddkP), so a check to make sure that line( '.' ) > 1 for the up and < line( '$' ) for the down might not be a bad idea. I DO like this idea and, with the above modifications, am adding it to my list of mappings so please don't take the suggestions the wrong way.

*Sigh* Try swapping up when on the last line. . . Need to add yet another check in there; my final version: function! MySwapUp() if ( line( '.' ) > 1 ) let cur_col = virtcol(".") if ( line( '.' ) == line( '$' ) ) normal ddP else normal ddkP endif execute "normal " . cur_col . "|" endif endfunction function! MySwapDown() if ( line( '.' ) < line( '$' ) ) let cur_col = virtcol(".") normal ddp execute "normal " . cur_col . "|" endif endfunction noremap <silent> <S-Up> :call MySwapUp()<CR> noremap <silent> <S-Down> :call MySwapDown()<CR>

Use normal! instead of normal... Who knows what people might have mapped on d, k or P :)
