Launcher is a global menu that houses all Modeler tools, organized into intuitive categories. The tool description and its hotkey are displayed at the bottom.

By default, Launcher can be opened by pressing the Tab key. However, you can reassign this key through the hotkey editor, which can be found on the Modeler shelf.

By default, Launcher opens in such a way that its window is centered around the mouse cursor. There is also another way, where the window opens so that the last launched tool is under the cursor. To use this feature, enable the "Open Launcher and Context Sensitive Menus at Last Tool" option in the Modeler's settings window. There, you can also adjust the transparency and size of Launcher.

Since Launcher is activated by pressing the Tab key, you can access the classic Houdini Tab menu by pressing Shift+Tab.
