Suppose I have the following two lines in a function:
execute "normal! o"
execute "normal! S"
Is there a way to combine these so it is simpler, for example:
execute "normal! o<c-o>S"
It seems I need to 'escape' the <c-o> somehow.

In execute parameters, you need to escape special characters sequences with \:
execute "normal o\<c-o>S"
But this will not let you in insert mode. You could add
startinsert
to force insert mode, but it will not respect autoindent. I don't know how to get around that.
You might as well go for a list of instructions:
normal! o
normal! S
startinsert
execute is no more needed, making the code quite clear.

sure, but wouldn't you need
execute "..."if you're using any control sequence, such as in your first code line?– David542Commented Jun 15, 2020 at 5:23 -
@David542 Yes, indeed. I edited my post to make it clearer what I meant.– BiggybiCommented Jun 15, 2020 at 5:40

Well, typically it’s unlikely you want to use someone’s mapping for S when you do
:normal Sin a plugin—but without the bang, if I havennoremap S anythingit will take effect! Its like noremap for normal; it’s become something of a best-practice, and it’s good defensive programming. The idea is to use it unless you know you want to invoke a mapping via normal– D. Ben Knoble ♦Commented Jun 15, 2020 at 12:36
<c-o>withexecute "normal! o\<C-o>S". See:help expr-quotewhich explains how double quoted strings work...
