Video tutorials are great but, it’s very difficult for authors to articulate every keystroke and mouse-click, along with performing everything else. Even when it can be done, it tends to make for longer tutorials because the author has to slow down.
Well, here’s a tool for video tutorial authors that may prove to be quite helpful.
Using the Windows open-source utility called AutoHotkey, Salvatore Agostino Romeo has created a compiled script that displays every keystroke and mouse-click that’s performed.
He writes:
…I noted there are many tutorials to see, but in almost all you don’t know what the
author is doing with keyboard and mouse. So I made a little program (about 200KB)
to help tutorial writers: osdHotkey. It is a standalone program: just run
it (no-install). It is open-source too.
Salvatore provides the source code, documentation, and a link to the scripting tool used to create it (AutoHotkey). You can also change the foreground and background colors, the size of the window, and you can use it to capture keystrokes for applications other than Blender.
