Describe your question, feature request, or bug.

My work scenario is in the mac, open the iTerm2 terminal and connect the remote Linux machine via ssh. When opening the vim with plugin LeaderF, everything works fine except the paste function. Here are two questions that bother me:

1. The default key bind for pasting from the official doc is <C-V> or <S-Insert>, but there are unuseful in my terminal. <C-V> does nothing, but I found it will move my cursor to the top of the search result view if I moved down. <S-Insert> includes the Insert key that does not exist on my computer, so I ignore it.
2. My last experience about copying into a terminal is by <cmd+v>, it's no use and exactly freezes my vim every time! I cannot input anything except <C-C> to quit. And that multi-continual <C-C> leads to an error in vim console, logs are here:

Error detected while processing function leaderf#Any#start[4]..leaderf#LfPy:

vim.error: Vim:vim.error: Vim(let):E684: list index out of range: -1

Steps to reproduce

1. vim
2. :Leaderf file
3. cmd + v

Actual behaviour

And the vim will freeze, only the key <Ctrl+C> will terminate LeaderF with the error introduced above.

Expected behaviour

paste into the command line of LeaderF

<cmd+v>, it's no use and exactly freezes my vim every time!

It's known issue: #427

I think ctrl-v should work if you remove \ '<C-V>': [] from

let g:Lf_CommandMap = {
  \ '<C-R>': [],
  \ '<F5>': ['<C-R>'],
  \ '<C-V>': []
  \ }

let g:Lf_CommandMap = {
  \ '<C-R>': [],
  \ '<F5>': ['<C-R>'],
  \ '<C-V>': []
  \ }

Sorry to paste the wrong configuration, I have removed the '<C-V>': [] in my config, but nothing happened after input.

I don't know what's wrong, and I change to some handy solutions:

1. remove the suffix <CR> in the shortcut for each Leaderf command
2. edit the query in vim's command line for full editor key bindings enabled

And command + V problem I will query in that issue.

It's because your vim feature is -clipboard. Ctrl-v can paste the words from the * register.
