Move cursor to beginning of non-whitespace characters in a line in Vim

If I understand correctly - from :h ^:

^ To the first non-blank character of the line.
  |exclusive| motion.

(in contrast to 0, which gets you to the beginning, regardless of whitespace or not)

Instead of pressing ^ you can press _(underscore) to jump to the first non-whitespace character on the same line the cursor is on.

+ and - jump to the first non-whitespace character on the next / previous line.

(These commands only work in normal mode, not in insert mode.)

Also possibly useful: + and - will move the cursor up or down, respectively, to the first non-blank character.

below is a snippet from by .vimrc
^[[1~ is created by pressing ctrl+v and Home

"jump to first non-whitespace on line, jump to begining of line if already at first non-whitespace
map <Home> :call LineHome()<CR>:echo<CR>
imap <Home> <C-R>=LineHome()<CR>
map ^[[1~ :call LineHome()<CR>:echo<CR>
imap ^[[1~ <C-R>=LineHome()<CR>
function! LineHome()
  let x = col('.')
  execute "normal ^"
  if x == col('.')
    execute "normal 0"
  endif
  return ""
endfunction
