" map <Leader> <Plug>(easymotion-prefix)
" " Jump forward.
" nmap <Leader>e <Plug>(easymotion-W)
" " Jump backward.
" nmap <Leader>E <Plug>(easymotion-B)

" The missing motion for Vim.
" NOTE Requires 'IdeaVim-Sneak' plugin.
" `s{char}{char}` and two chars - sneaking forward.
" `S{char}{char}` - sneaking backward.
" `;` or `,` - continue sneaking.
set sneak

" Emulation of the `NERDTree` plugin.
" `r` - recursively refresh the current directory.
" `R` - recursively refresh the current root.
" `K` - navigate to the first sibling of current file/directory.
" `J` - navigate to the last sibling of current file/directory.
" `o` (<CR>) - open file in a new tab.
" `O` - recursively open the selected directory.
" `P` - jump to the root node.
" `p` - jump to current nodes parent.
" `A` - zoom (maximize/minimize) the NERDTree window.
" `v` - split vertically.
" `h` - split horizontally.

" {motion} (for example, by `.` repeating) and perform the exchange.
" `cxx` - like `cx`, but use the current line.
" `X` - like `cx`, but for Visual mode => without `.` repeating.
" `cxc` - clear any {motion} pending for exchange.
Plug 'tommcdo/vim-exchange'
