Terminal Vim <esc>, <F4> key mappings lead to several problem.

For example, if you press twice, in terminal vim, it will insert S in your buffer.

Hi,

This bug appears on every plugin which splits window(undotree, qf, gs, tagbar) in terminal vim
e.g. leader u, Up puts 'A' in text

Thanks.

Yeah, I'm working on it. Will be fixed soon.

Basically, I will just prevent using <ESC> directly for terminal Vim. instead, use <leader><esc> or user custom mappings.

This is same solution as old exVim.

I'm getting insertion in text without pressing ESC. (e.g. <leader>u, <Up>) Is this the same issue?

This issue is caused by the vim terminal keycode. Vim use ^[ keycode simulate special key such as <UP>, <F1-12> in terminal. The ^[ represent to the key <ESC>. This key by default is used as exVim's plugin-window closing key.

To solve this problem. I just use <leader><ESC> as the close window key mapping in Terminal.
