Keystroke visualizer for GUI version Emacs

This package is a keystroke visualizer for GUI version Emacs.
You no longer need to use external tools to display keystrokes when creating screencasts!

Install

Keypression is available in melpa. You can install keypression via package-install M-x package-install [ret] keypression [ret]

Usage

Add the following to your .emacs. (This is not necessary if you installed from MELPA)

(require 'keypression)

Then, if you want to display keystrokes, do the following:

M-x keypression-mode

Run it again to turn it off.

The default is a simple display, so you can customize it as follows.

(setq keypression-use-child-frame nil
      keypression-fade-out-delay 1.0
      keypression-frame-justify 'keypression-left-justified
      keypression-cast-command-name t
      keypression-cast-command-name-format "%s  %s"
      keypression-combine-same-keystrokes t
      keypression-font-face-attribute '(:width normal :height 200 :weight bold))

To change the display position, do the following.

(setq keypression-x-offset 100
      keypression-y-offset 100)

Restriction

On Windows, child-frame works well, but on Linux (GTK+3) and macOS versions, child-frame is disabled by default because of a problem.
If child-frame is disabled, all the input key display frames are displayed on the taskbar.
I think there is no problem to create a screencast, but it seems to be difficult to switch applications.
