Screencast Keys earns its place in the blender_extensions library for turning key presses, mouse actions, and the last operator into a customizable on-screen display. A demo video is available, and the tutorial documents each option in detail.
Screencast Keys shows the keyboard and mouse status inside Blender, along with the operator executed last. The add-on is intended for making Blender tutorials. You can change which area, region, or window the status appears in.
The display is heavily customizable. Options cover text color, shadow, background planes and modes, font size, margin, line thickness, and the size of the figure that shows held mouse status. Origin, align, and offset settings control where texts and figures appear, and repeated keys can be shown as a single string such as Tab x5. Max Event History limits how many key events are shown, while Display Time controls how long each event stays visible.
Additional settings include custom mouse images, enabling the add-on on Blender startup, adding its menu to the sidebar or Viewport Overlays, and toggling the display with Shift + Alt + C. It is licensed under the GNU General Public License v3.0 or later.
Screencast Keys is best for recording and building Blender tutorials where on-screen keyboard, mouse, and operator feedback is needed.
Screencast Keys is completely free to download and use.
Screencast Keys lists compatibility with Blender 4.2 LTS and newer. On Blender 4.2 or later, every event can be collected without the Get Event Aggressively option, which was only needed on Blender 4.1 or earlier. That older option is experimental and could crash Blender in specific environments. If you are on a version outside the listed range, check the developer's page on GitHub to confirm behaviour before relying on it.
Screencast Keys can be added to Blender by dragging and dropping the add-on into Blender, or by downloading it and installing from disk. After installation, you can enable it manually or turn on the Enable On Startup option so it activates when Blender launches. Its menu can be added to the sidebar or the Viewport Overlays through Preferences, and the panel location can be adjusted using the Space and Category options. The display itself toggles on and off with Shift + Alt + C.
Screencast Keys includes a Show Mouse Events option that displays events from the mouse. Its Mode setting offers Event History, Hold Status, or Event History plus Hold Status. When Use Custom Mouse Image is enabled, you can assign separate images for the base state and for the left, right, and middle buttons, with left, right, and middle images overlaid on the base in Overlay display mode. The Mouse Size option controls the figure size used for hold status.
Screencast Keys is listed as free in this catalog and is released under the GNU General Public License v3.0 or later. The extension notes that it does not require special permissions. The add-on can also be updated directly from Preferences within Blender. For the latest licensing terms, versions, and updates, the developer's page on GitHub is the place to check.
