This displays a short help message, namely the string produced by the `kbd-help' property at point. If `kbd-help' does not produce a string, but the `help-echo' property does, then that string is printed instead. A numeric argument ARG prevents display of a message in case there is no help.

If a timer is already active, there are two ways to make the new value take effect immediately. After setting the value, you can first call `help-at-pt-cancel-timer' and then set a new timer with `help-at-pt-set-timer'. Alternatively, you can set this variable through Custom. This will not set a timer if none is active, but if one is already active, Custom will make it use the new value.

If the value is t, the string obtained from any `kbd-help' or `help-echo' property at point is automatically printed in the echo area, if nothing else is already displayed there, or after a quit. If both `kbd-help' and `help-echo' produce help strings, `kbd-help' is used. If the value is a list, the help only gets printed if there is a text or overlay property at point that is included in this list. Suggested properties are `keymap', `local-map', `button' and `kbd-help'. Any value other than t or a non-empty list disables the feature. This variable only takes effect after a call to `help-at-pt-set-timer'. The help gets printed after Emacs has been idle for `help-at-pt-timer-delay' seconds. You can call `help-at-pt-cancel-timer' to cancel the timer set by, and the effect of, `help-at-pt-set-timer'. When this variable is set through Custom, `help-at-pt-set-timer' is called automatically, unless the value is `never', in which case `help-at-pt-cancel-timer' is called. Specifying an empty list of properties through Custom will set the timer, thus enabling buffer local values. It sets the actual value to nil. Thus, Custom distinguishes between a nil value and other values that disable the feature, which Custom identifies with `never'. The default is `never'.
