Ambiguity of snippets keymap

[LittleNewton]

["<c-e>"] = cmp.mapping(
    function()
        cmp_ultisnips_mappings.compose { "expand", "jump_forwards" } (function() end)
    end,
    { "i", "s", --[[ "c" (to enable the mapping in command mode) ]] }
),

In autocomplete.lua, there is ambiguity.

Now I have a snippet:

snippet head "Head of Hexo Blogs"
title: ${1:title}
author: Peng Liu
cover: /images/`!p import os
base_name, _ = os.path.splitext(snip.fn)
snip.rv = base_name`/cover.png
date: `date +"%Y-%m-%d %H:%M:%S"`
tags:
	- ${2:tag}
categories:
	- ${3:type}

And another short snippet:

snippet aj "Markdown keyboard" i
<kbd>${1:key}</kbd>
endsnippet

The first snippet contains multiple placeholders.

In the first snippet instance, if I type aj with the intention of keyboard typing, the push of Ctrl e will have two different meanings:

• expand aj
• or jump-forward to the next placeholder.

I wanted it to take the expansion action but now it does nothing.

I see. I usually don't work on snippets within a snippet, but feel free to add another binding that's for expanding only.
