I want to start a line with > but it turns into quote automatically how can i disable it
“Escape” it by putting a backslash before it: \>. https://help.obsidian.md/syntax#Escaping+Markdown+Syntax
… Or you can try to neutralize the text decoration characteristic of blockquote by using CSS. This way, you won’t have to enter \ before > every time.
And if/when switching to another software, you won’t have to clean up all the \ before >, even though this can be done fairly quickly using the bulk replacement function in text editors.
The disadvantage is that if you do use blockquotes from time to time, their text decoration will also be neutralized, and they will look like regular text.
In this case, the option suggested by @CawlinTeffid would be more appropriate.
Unfortunately, I don’t have a ready-made solution for you, and due to certain circumstances, I cannot create one for you. I’m sorry.
