Vim: ignore case in “f” and “t” motion commands

Question

Vim :set ignorecase command do not affect "f" and "t" motion commands in my vim config.

Is there any option or hack that makes this commands to ignore case?

Answer 1

I would suggest something like:

function! ForwardLookup()
    " get next key pressed
    let c = nr2char(getchar())
    let old_search_pattern = @/
    " Use of \V enables very-nonmagic pattern
    exec 'normal /\c\V' . escape(c, '\/') . nr2char(0x0d)
    let @/ = old_search_pattern
endfunction
nnoremap f :call ForwardLookup()<CR>

Answer 2

I don't think you can make it ignore case on all commands. However, for your purposes, remapping the keys would get the desired result. You can do this by adding the following to your .vimrc file:

"remap the f and t keys to be case insensitive in visual, command, and normal mode.
map F f
map T t
