Single line indents

What I’m trying to do

Is there a way to indent only the first line of a paragraph using the Tab key?

Things I have tried

Maybe I’m just blind, but I haven’t seen it mentioned anywhere in the settings, forum or help doc. I tried turning off everything regarding indentation, but nothing seems to work

###Thank you for your time!

Markdown doesn’t care of tabs in paragraphs, only in lists.
Check out my theme, if offers paragraph indentation and some more

Heya!
Best solution I have found for that is to use a .css snippet with this code:
.cm-line, p {
text-indent: 1.5em;
}

It also affects the yaml/frontmatter in Source mode but I’ve no idea how to fix that. You don’t have to press tab or anything when this snippet is active, everything is indented automatically. Feel free to change the size of the indent.
