For example moving the mouse pointer over the mode-line, menu entries or some buttons, buffer lines in grep-mode. Normaly show_help_echo delegates all work to show-help-function. This mechanism is used to popup tooltips. When show-help-function is nil (like on text only displays or when tooltip-mode is disabled) show_help_echo does the job itself by displaying those strings in the echo-area.
