DE Launcher: Ultimate Guide to Features & Setup

What DE Launcher is

DE Launcher is a lightweight application launcher designed to speed up app access, file opening, and system actions through a minimal, keyboard-focused interface. It’s built for users who prefer fast, customizable workflows over bulky start menus.

Key features

  • Quick search: Instant fuzzy search for apps, files, bookmarks, and system settings.
  • Keyboard-first control: Launch, navigate, and execute commands without leaving the keyboard.
  • Custom actions: Create macros, shell commands, and URL shortcuts.
  • Plugins/extensions: Extend functionality with community or custom plugins (e.g., clipboard history, calculator, media controls).
  • Theming & appearance: Light/dark modes, font choices, and compact layouts.
  • Cross-platform support: Available on major desktop platforms (Windows, macOS, Linux) with platform-specific integrations.
  • Low resource use: Minimal memory and CPU footprint for quick responsiveness.

Installation and initial setup

  1. Download the latest installer for your OS from the official release page.
  2. Run the installer and follow on-screen prompts (macOS: drag to Applications; Linux: use provided package or AppImage; Windows: run installer).
  3. On first launch, allow any requested accessibility or input permissions so global hotkeys work.
  4. Set a global hotkey (recommended: Alt+Space or Ctrl+Space) to open DE Launcher instantly.

Basic configuration

  1. Open Preferences from the launcher (hotkey → type “preferences” or click settings).
  2. Set search scope: include/exclude directories, app stores, and browser bookmarks.
  3. Configure indexing frequency and file types to balance speed vs. freshness.
  4. Choose theme and font size for readability.
  5. Enable or disable telemetry (if available) according to your privacy preference.

Creating and using custom actions

  1. Go to Actions → New Action.
  2. Choose action type: application, script/shell command, URL, or plugin trigger.
  3. Enter a name, an easy-to-type keyword, and the command or path.
  4. Assign an icon and optional hotkey for one-tap execution.
  5. Example: Create “notes” action that opens your notes app with a specific notebook: command: /usr/bin/notes-app –notebook Work.

Plugins and advanced integrations

  • Install plugins from the built-in marketplace or by placing plugin files in the extensions folder.
  • Popular plugins: clipboard manager, calculator, web search, music player controls, system monitor.
  • For developers: write plugins using the provided SDK (JavaScript/Python bindings commonly supported). Include manifest.json, main script, and icon.

Tips for power users

  • Use multi-step commands: chain shell commands with && or scripts.
  • Create aliases for long paths or frequently used command-line tools.
  • Map workspace or virtual desktop switching to keywords.
  • Index cloud storage locations (Dropbox, OneDrive) selectively to avoid slow searches.
  • Backup your settings and actions.json to sync across machines.

Troubleshooting

  • Launcher not opening: confirm global hotkey permission and no conflicting app.
  • Slow searches: reduce indexed folders or increase indexing interval; check disk health.
  • Plugin errors: update the plugin, check logs in the developer console, or disable conflicting plugins.
  • Permission issues on macOS: grant Accessibility and Full Disk Access if file search fails.

Security and privacy considerations

  • Limit indexing to non-sensitive folders if you prefer local-only search.
  • Review plugin source code before installing third-party plugins.
  • Use secure vaults or passphrase-protected apps for sensitive command triggers.

Example workflows

  • Rapid app switching: hotkey → type 2–3 letters of app → Enter.
  • Quick notes capture: hotkey → “capture” action bound to a script that appends text to a daily markdown file.
  • Web searches: hotkey → “g query” to open Google search, or query-specific plugins for Stack Overflow, MDN, etc.

Final setup checklist

  1. Install and set global hotkey.
  2. Configure search scope and indexing.
  3. Create 5–10 custom actions for daily tasks.
  4. Install one productivity plugin (clipboard or calculator).
  5. Backup or export settings.

This guide gives a complete path from installation to advanced customization so you can make DE Launcher a central part of a faster, keyboard-driven workflow.
