How do I get keystrokes displayed in the echo area immediately?
For example: when I enter the key sequence C-u j, it will not display in the echo area immediately, but then I press key k, and I discover that I was making a typo beforehand. So, I think it will helpful for a newbie like me when I hit some keys to call a command for the echo area to show them immediately.
You are looking to adjust the value of the
variable
echo-keystrokes.
You can read its docstring by entering C-h v echo-keystrokes (or
M-x describe-variable echo-keystrokes):
Documentation:
Nonzero means echo unfinished commands after this many seconds of pause. The value may be integer or floating point. If the value is zero, don't echo at all.
Note that you cannot set the value to 0 and have it echo instantaneously, but you can set it to an arbitrarily small number, which will feel instantaneous. You can therefore put something like the following in your init file:
(setq echo-keystrokes .1)
