Documentation

Toggle uncloaking of invisible text near point (Reveal mode).

Reveal mode is a buffer-local minor mode. When enabled, it reveals invisible text around point.

Also see the reveal-auto-hide variable.

This is a minor mode. If called interactively, toggle the Reveal mode mode. If the prefix argument is positive, enable the mode, and if it is zero or negative, disable the mode.

If called from Lisp, toggle the mode if ARG is toggle. Enable the mode if ARG is nil, omitted, or is a positive number. Disable the mode if ARG is a negative number.

To check whether the minor mode is enabled in the current buffer, evaluate the variable reveal-mode(var)/reveal-mode(fun).

The mode's hook is called both when the mode is enabled and when it is disabled.
