How to make lists with dashes rather than bullets?

just trying to have lists be started by dashes (-) rather than the normal bullets/dots

u can use css snippet here to change that.

.markdown-preview-view ul li::marker {
    content: '– ';
}
.markdown-source-view.mod-cm6 .list-bullet:after {
    content: "–";
}

see this help page on how to save css snippets
