Hovered Tooltip

[Froxcey]

I write Typescript and I'm starting to write Rust code. I have installed both coc-tsserver and coc-rust-analyzer. Everything is perfectly fine when writing code, but I want the hover tooltip when reading other people's code. Is there anyway I can hover something in normal mode using the vim cursor and use a keybind to show documentation tooltip?

" Use K to show documentation in preview window.
nnoremap <silent> K :call ShowDocumentation()<CR>

function! ShowDocumentation()
  if CocAction('hasProvider', 'hover')
    call CocActionAsync('doHover')
  else
    call feedkeys('K', 'in')
  endif
endfunction

Thanks! That works perfectly

You can use <MouseMove> key-mapping on latest gvim >= 8.2.4674, see :h <MouseMove>

Not in Vim?

It's gvim only, check the doc.
