RT, I don’t know whether I pressed which key by mistake, opened a file and entered new content. There is always a highlighted background. How do I remove it, please?

Visual inspection turned on the highlight search, and the search keyword was accidentally lost.

The operation mode is to enter/.

Presumptive recovery method (alternative):

  1. :set nohlsearch
  2. /mamashuosuibianshuruyhuicheshishi
