I can use K to show the man pages in Vim before I install coc.nvim. And when I am using coc.nvim to do the same thing, instead of man pages, the documentation is in a hover. But sometimes, the text cannot be displayed at one time, like this:
I have tried many ways to scroll the hover area, j, Ctrl+j, Shift+j, Ctrl+p, Shift+p, Tab, j..., but they didn't work.
So what can I do to scroll the documentation so that I can read the whole text
Check :h coc#float#has_scroll:
if has('nvim-0.4.0') || has('patch-8.2.0750')
nnoremap <silent><nowait><expr> <C-f> coc#float#has_scroll() ? coc#float#scroll(1) : "\<C-f>"
nnoremap <silent><nowait><expr> <C-b> coc#float#has_scroll() ? coc#float#scroll(0) : "\<C-b>"
inoremap <silent><nowait><expr> <C-f> coc#float#has_scroll() ? "\<c-r>=coc#float#scroll(1)\<cr>" : "\<Right>"
inoremap <silent><nowait><expr> <C-b> coc#float#has_scroll() ? "\<c-r>=coc#float#scroll(0)\<cr>" : "\<Left>"
vnoremap <silent><nowait><expr> <C-f> coc#float#has_scroll() ? coc#float#scroll(1) : "\<C-f>"
vnoremap <silent><nowait><expr> <C-b> coc#float#has_scroll() ? coc#float#scroll(0) : "\<C-b>"
endif
My vim version was too low, after updating it, the problem had been solved
Shift-kwill activate the lsp hover but leave you in visual mode, in the buffer. If you typeshift-kagain focus will move to the hover and you can scroll around using all the usual keys (j, k, C-f, C-d, C-b, page-up, page-down etc) and type q to dismiss the popup.
