I have looked through several community plugins, but nothing shows up for what I’m trying to achieve, but on MacOS, I hold the Option and Shift buttons at the same time and pressed the hyphen button three times to make three long dashes, then held the Option button and pressed 8 to make the dot, and then those three long dashes again.
Haven’t used a Mac in a while, but I think you’re talking about three em-dashes, a dot point, and three more em-dashes.
One option is to the whole string:
———•———
… paste it into a template, and assign a shortcut to inset the template. You could do this with a templating plugin like Templater or an text-inserting plugin like Text Format.
Another is to use a Windows program such as PowerToys to map each character to a keyboard shortcut. (I personally use right Alt+- for em-dash and left Alt+- for en-dash.)
And another option is to memorize their alt codes. For example, hold Alt while typing 0 1 5 1 to insert an em-dash. (I do not do this and had to look it up just now.)
If you are using this dash-dot thing to mark something like a scene break in fiction, I recommend using a Markdown “thematic break” instead. Obsidian’s help calls it a “horizontal rule”.
You can use CSS to make it look more like the design you’ve been using when it’s rendered (like in Reading View, Live Preview).
I think the dot character might be called a “bullet” (maybe with an adjective, like “round bullet”).
