elisp: Recording Input
38.13.2 Recording Input
-----------------------
-- Function: recent-keys
This function returns a vector containing the last 300 input events
from the keyboard or mouse. All input events are included, whether
or not they were used as parts of key sequences. Thus, you always
get the last 300 input events, not counting events generated by
keyboard macros. (These are excluded because they are less
interesting for debugging; it should be enough to see the events
that invoked the macros.)
A call to ‘clear-this-command-keys’ (Command Loop Info)
causes this function to return an empty vector immediately
afterward.
-- Command: open-dribble-file filename
This function opens a “dribble file” named FILENAME. When a
dribble file is open, each input event from the keyboard or mouse
(but not those from keyboard macros) is written in that file. A
non-character event is expressed using its printed representation
surrounded by ‘<...>’. Be aware that sensitive information (such
as passwords) may end up recorded in the dribble file.
You close the dribble file by calling this function with an
argument of ‘nil’.
See also the ‘open-termscript’ function (Terminal Output).
