gud-tooltip-tips

gud-tooltip-tips is a compiled Lisp function in `gud.el'.

(gud-tooltip-tips EVENT)

Show tip for identifier or selection under the mouse.
The mouse must either point at an identifier or inside a selected
region for the tip window to be shown. If `gud-tooltip-dereference' is t,
add a `*' in front of the printed expression. In the case of a C program
controlled by GDB, show the associated #define directives when program is
not executing.

This function must return nil if it doesn't handle EVENT.
