Briefly highlight the current line in Emacs.
(require 'nav-flash) (nav-flash-show)
Nav-flash temporarily highlights the line containing the point, which is sometimes useful for orientation after a navigation command.
There is no user-level interface for this library; it is only used by other Lisp libraries. However, you might find it useful to call nav-flash-show in your ~/.emacs file. For example, the following hook causes a flash to appear after navigating via imenu:
(add-hook 'imenu-after-jump-hook 'nav-flash-show nil t)
This library reuses an overlay defined in compile.el, but should not affect the normal use of compile.el / next-error.
pulse.el provides similar functionality and is included with Emacs. This library can use pulse.el, but does not do so by default, because pulse.el uses sit-for, breaking this type of construct:
(nav-flash-show) (with-temp-message "message here" (sit-for 2))
When using an overlay and timer for cleanup (as nav-flash does by default) the flash and message appear simultaneously.
nav-flash.el is also simpler than pulse.el.
