You can use the
vim-columnmove plugin and visual-mode block-wise selection to do this. The plugin imitates various groups of motions, and in this case:
columnmove-f and its variants are the commands for bringing cursor to the position assigned by a character in the same column.
This group has six keymappings, that is,
columnmove-,. Each of them are the imitations of
, commands, but work in vertical direction.
The motions are mapped to
<M-f/F/t/F> by default, but since those combinations were interpreted as something else in my case, I used
map <leader>f <Plug>(columnmove-f)
map <leader>F <Plug>(columnmove-F)
map <leader>t <Plug>(columnmove-t)
map <leader>T <Plug>(columnmove-T)
Then, by pressing
d<C-v>\ti, I could delete the characters
e. Without block visual mode, it deletes the first and second lines.
