How do I delete all lowercase marks in the current buffer at once?

Explanation

Marks accumulate as you work — ma, mb, mc and so on record positions for later jumps. Over time, especially in long editing sessions, the mark list fills with stale entries that clutter :marks output and can confuse navigation. :delmarks! clears all lowercase marks (a–z) in the current buffer in one command.

How it works

• :delmarks {marks} removes specific marks by letter or range: :delmarks ab, :delmarks a-f
• :delmarks! (with !) removes all lowercase marks (a–z) in the current buffer simultaneously
• It does not affect uppercase (A–Z) global marks, special auto-marks ('[, '], '^, '.), or numbered marks ('0–'9)

Example

Before:

:marks
mark line  col text
 a      5    0  function setup()
 b     12    4  local config = {}
 c     88    0  end

Run :delmarks!, then:

:marks
mark line  col text
 ^     12    4  (last insert position only)

All user-set lowercase marks are gone.

Tips

• To delete only a specific range: :delmarks a-e removes marks a through e
• To also delete global uppercase marks: :delmarks A-Z
• To reset marks automatically when entering a buffer, add to your vimrc:

  autocmd BufReadPost * delmarks!
  

• Use :marks to review all current marks before and after deleting
• The :delmarks command was introduced in Vim 7.0
