Question

I added the following to my .vimrc file:

nnoremap <silent> <F5>!python %

That should run the current file in Python when I press F5. Instead, it gives the following error:

Trackback (most recent call last):
  File "<string>", line 1, in <module>
  File "<string>", line 349, in f_with_update
  File "<string>", line 358, in run_this file
NameError: global name 'send' is not defined
Press Enter or type command to continue

If I re-mapped F5 manually everytime I run VIM, this command works:

:map <silent> <F5>!python %

I don’t recall mapping anything to F5, and my .vimrc file doesn’t contain any mapper.
Any idea what’s happening?

Answer 1

<F5> is probably mapped elsewhere. Try :verbose nmap <F5> to see where.
