vim mapping question. How can I make a map to :r! <script> execute right away?

Question

I have a python script called showdate.py which I want to map to

I do this by:

map <F2> :r! showdate.py

in my _gvimrc file.

The problem is that I have to press enter when I press F2 to execute instead of executing immediately. Any ideas?

Thanks!

Answer 1

在映射末尾添加换行符：

map <F2> :r! showdate.py<CR>

Answer 2

I'm not sure if this will work in your case but I remember using '' to simulate a carriage return. So your line will look like:

map <F2> :r! showdate.py <CR>
