I'm trying to execute simple commands in the vim terminal mode, but cannot get it to work. For example, I tried

nmap <F12> :let $VIM_DIR=expand('%:p:h')<CR>:terminal<CR>cd $VIM_DIR<CR>

to open a terminal in the directory of the current file, but the final <CR> is ignored. I also tried term_sendkeys("","\<CR>") but that didn't have any noticeable effect at all.

  • For me this works, but only if I map it to a function key below F10, very strange...

  • Is it Vim or Neovim?

I tested that this works. It assumes that the terminal is opened in buffer 2.
You can check which buffer the terminal is open in with :ls.

:terminal
CTRL-W W 
:let  $VIM_DIR=expand('%:p:h')
:call term_sendkeys(2, "cd $VIM_DIR\n")
:call term_sendkeys(2, "pwd\n")

Also your initial command worked for me.

nmap <F12> :let $VIM_DIR=expand('%:p:h')<CR>:terminal<CR>cd $VIM_DIR<CR>

It maybe that you are testing this mapping using keys that are already mapped. You can review the nmap mappings with:

:nmap

Or a specific mapping with:

:verb map <F12>

verb (verbose) tells you where the mapping was defined (file and line).
