Crontab, yellow background

Yellow-Background

After running ¨sudo crontab -e¨.
I accidentally clicked the mouse button before pressing ¨insert¨ on the keyboard.
As a result every number 28 has this yellow background as in image.
The only way I can seem to get rid of it is with
dnf remove vim-enhanced, not ideal.
Google was not much help to me.
Fedora 42 Beta, Xfce.

That just looks like highlighting the search results.

I only see this when I´m in the crontab. But how do I get rid of it.

You can turn of search highlighting using :set nohlsearch from normal mode - not sure how familiar you are with vim, but if you see -- INSERT -- in the bottom left corner of the screen then you’re in insert mode and need to press Escape first.

Alternatively, search for a pattern that won’t exist in the file - in normal mode again, press / for search, then type a longish string of random characters e.g. /qnwqel1n2321n3.
In the unlikely event that qnwqel1n2321n3 appears in your crontab or any other file you edit with vim as root then it would end up highlighted yellow and you’d need to search for another random string to stop it.

Thank you Thomas, did the trick.
