I'm trying to delete the mark ' (single quote) but I dont know how. I'm doing delm \' bu开发者_如何学运维t it doesn't work. I also tried every combination I could think of.

I realize this is more a Vim script question, but I couldn't find it anywhere.

Why do you want to delete that mark? It's an automatic one (excerpt from :he ''):

'' `` To the position before the latest jump, or where the
last "m'" or "m`" command was given. Not set when the
|:keepjumps| command modifier was used.
Also see |restore-position|.

Don't understand the question, are you talking about markers (:help mark)? If so, ' is not a valid marker, vim only supports m{a-zA-Z} Well, ' is a marker but not a one you can delete/change.

' has special meaning in vim (:help ''):

''  ``          To the position before the latest jump, or where the
            last "m'" or "m`" command was given.
