how recover recent keystrokes typed in emacs? i'm long-time emacs user (30 years), every mistype key sequence, unusual happens, , want know sequence of chars typed, compared thought typed. know there's command shows couple dozen of recent chars typed, can't remember is, , can't seem find either. example, in dired-mode, move cursor file, , type ! run command on file, type other sequence mistake, , see i've selected files in dired buffer—all files marked *. i'm trying debug typing in situation.

type c-hl, invokes view-lossage.
