F15 Key Simulator

F15 is a program that simulates the press of the F15 key on a Windows keyboard every 60 seconds.

The F15 key code corresponds to the "Verr Num" (Num Lock) key on the keyboard.

Description

Welcome to F15! 😊 This project is designed to simulate keypresses of the Num Lock key at regular intervals. It is open source and available under the MIT license. Note: This program is designed for Windows only.

Use Cases

1. Preventing Screen Lock:

   • Use F15 to simulate keypresses and prevent your computer from locking the screen due to inactivity.

2. Presentation Mode:

   • Use F15 during presentations to prevent the screen from going to sleep or the screensaver from activating.

3. Long-running Processes:

   • Keep long-running processes active by simulating keypresses, ensuring they are not interrupted by system inactivity.

4. Monitoring Dashboards:

   • Use F15 to keep monitoring dashboards (e.g., Grafana, Kibana) active and prevent them from timing out due to inactivity.

5. Remote Session:

   • Keep your remote desktop session active by simulating keypresses, ensuring you stay connected without interruptions.

Features

• Easy to use: Simple and straightforward to set up.
• Low Resource Usage: Very low CPU and memory consumption.
• High Performance: Optimized for maximum performance.
• Safe: Open source code ensures transparency and security.
• Extensible: Easy to customize and extend.
• Run at Startup: Configure Windows to run F15 at startup to ensure it is always active when your computer boots.

Installation

To install this program, follow these steps:

1. Clone the repository:

   git clone https://github.com/nbigot/f15.git
   cd f15

2. Build the project:

   1. Standard Build:

      cargo build --release

      Using the default compilation settings, the F15 program will not print anything to the console when running and the keypress frequency is 60 seconds.

   2. Build for release but change the frequency to 10 seconds:

      export SLEEP_DURATION=10
      cargo build --release

      Set the keypress frequency is 10 seconds.

   3. Verbose Release Build:

      cargo build --release --features "verbose"

      The program will output a message each time a simulated keystroke occurs.

3. Run the program:

   cd target/release
   ./f15

Usage

Here is how to use F15:

1. Execute f15.exe
2. The program will simulate keypresses of the Num Lock key twice every 60 seconds.
3. Press Ctrl+C when you want to stop the program.
