>>> nn, or :nnoremap, is a mapping from normal mode. So, all characters on the right-hand side will be executed by Vim as if you typed them from normal mode.
>>> In other words, Vim will enter the command line when it "types" the ':' character, inserts the rest of the line on the command line, and then...does nothing, because there is nothing else in the mapping for it to do.
>>> Follow up your mapping with "<CR>" or "<Enter>" to tell Vim to send the enter key for you.

> 2. :exec will not leave the cursor somewhere for input. You can't use a function in this way. If you want to use <Left><Left> repeatedly to place the cursor awaiting further input, you will need to have your function RETURN a value instead of executing it, and additionally use an expression map or abbreviation. See :help :map-<expr>

and, this just works - the only issue is I don't know how to repeat the
<left> here..
and, I really really don't understand how come this works but the
function version doesn't ...
confusing...

nn ,gg :!git add -A .;git commit -m "msg: ";git push origin master"<left>
