Q: How to remove debugging red dot in VSCode v1.28.2 I casually pressed a key, i don't know which one, i want to remove it from the view, i don't use VScode debugger at all.

I read the docs but it's unclear.

A: 
F9

or 

Click on the editor margin

or 

(Top Bar) Debug -> Toggle Breakpoint

or

(Icon on The left) Debug -> Breakpoint section -> Mouse Over -> Remove all breakpoints

should remove the breakpoint

A: To remove all breakpoints (red dot) you need go to Command Palette -> Debug and choose Remove all breakpoints from dropdown list.
More is in
Docs

A: Search for debug in settings, disable "glyph margin", and all related settings, this will disable the option to make debugging dots, if you just want to remove them all but not disable adding them, use the answers above.
