Anyway I tried C-h L, and I obtained:

C-s [isearch-forward]
 C-w [isearch-yank-word-or-char]
 < [isearch-printing-char]
 <mouse-movement> [gud-tooltip-mouse-motion]
 <mouse-movement> [gud-tooltip-mouse-motion]
 <mouse-movement> [gud-tooltip-mouse-motion]
 <mouse-movement> [gud-tooltip-mouse-motion]
 TAB [c-indent-line-or-region]
 TAB [c-indent-line-or-region]
 C-h l [view-lossage]

Another test gives:

C-s [isearch-forward]
 b [isearch-printing-char]
 u [isearch-printing-char]
 f [isearch-printing-char]
 l [isearch-printing-char]
 e [isearch-printing-char]
 n [isearch-printing-char]
 g [isearch-printing-char]
 t [isearch-printing-char]
 h [isearch-printing-char]
 < [isearch-printing-char]
 <mouse-movement> [gud-tooltip-mouse-motion]
 <mouse-movement> [gud-tooltip-mouse-motion]
 <mouse-movement> [gud-tooltip-mouse-motion]
 C-h l [view-lossage]

Is it related to gdb-mode I am using in another buffer? Perhaps the tooltip
of gdb-mode?
