Question

I am using the Show Marks plugin in vim to display where the marks are. The displayed marks can be toggled on/off with the \mt command. When I first open a document the marks are off like so:

Then about 4 seconds later with absolutely no action on my part, the left hand mark margin pops in like so:

I have three questions:

1. What are those default marks?
2. Why is it taking several seconds for it to get displayed?
3. How can I force the mark margin to activate/deactivate at start up?

From the help files:

let g:showmarks_enable=0

The default marks could be things like your last changed line.

:h `[

But they look like numerical marks, you may have just set them during a previous edit? I’m guessing they will go away if you type :delmarks 0 1 2 3 4 5 6 7 etc

Edit: This is also in the help files which probably explains the opening after 4 seconds:

ShowMarks is activated by the |CursorHold| |autocommand| which is triggered
every |updatetime| milliseconds.  This is set to 4000(4 seconds) by default.
If this is too slow, setting it to a lower value will make it more responsive.
