Pulsing Overlays
Manage temporary pulsing of faces and overlays.
This is a temporal decoration technique where something is to be
highlighted briefly. This adds a gentle pulsing style to the text
decorated this way.
The following are useful entry points:
`pulse-tick' - Cause `pulse-highlight-face' to shift toward background color.
Assumes you are using a version of Emacs that supports pulsing.
`pulse-momentary-highlight-one-line' - Pulse a single line at POINT.
`pulse-momentary-highlight-region' - Pulse a region.
`pulse-momentary-highlight-overlay' - Pulse an overlay.
These three functions will just blink the specified area if
the version of Emacs you are using doesn't support pulsing.
`pulse-line-hook-function' - A simple function that can be used in a
hook that will pulse whatever line the cursor is on.
