global-auto-composition-mode
global-auto-revert-mode
global-cwarn-mode
global-font-lock-mode
global-hi-lock-mode
global-hl-line-mode
global-reveal-mode
global-whitespace-mode

They are documented.

You are confusing two slightly different situations.

There are "true" global modes, which _only_ have a global effect, and
wouldn't make sense as a local mode; an example is `tool-bar-mode'.
Such modes are called FOO-mode because it is the obvious name (and
adding "global-" to the beginning would be pointless and annoying).

However there are global modes which are actually the effect of applying
a local mode globally, that is, they enable or disable the corresponding
local mode in all buffers.  Such modes are called global-FOO-mode,
because the fundamental mode in question is the local FOO-mode, and
global-FOO-mode is merely a convenient adjunct.
