Launcher

A blazing fast, keyboard-driven launcher for Windows, built with C++ and Qt.

Usage

• Press Alt + Space to bring up the search bar
• Type your query to see the results
• Add a prefix to the query to limit the results to a specific module
• Use the up / down arrow keys to navigate the result list
• Press Enter to execute the default action for the selected item
• Press Tab or left / right arrow keys to select other available actions for the highlighted item (if any)
• Press a specific shortcut (e.g., Ctrl + Shift + Enter) to execute a specific action (e.g., run as administrator)

Features

Launcher offers a set of built-in modules:

Apps Search

Find and launch applications installed on your system.

Configuration:

{
  "apps": [
    {
      "keywords": [
        "yourapp",
        "anothername"
      ],
      "name": "Your App",
      "path": "C:\\Program Files\\YourApp\\YourApp.exe",
      "icon": "C:\\Program Files\\YourApp\\Icon.png"
      // Optional. If not specified, the icon will be retrieved from the executable.
    }
  ]
}

On the first run, a default configuration file will be generated based on Start Menu items.
