1. Button Trigger
The Lenovo screenshot button (e.g., mapped to `F12`) executes a predefined script via AutoHotkey or PowerToys.

2. Capture and Processing

3. Dynamic File Naming
The script appends a timestamp (e.g., `YYYYMMDD_HHMMSS`) and user-defined prefix (e.g., `PROJECT_X_`) to the filename:

C:\Screenshots\PROJECT_X_20231015_143022.png

4. Storage Routing

5. Post-Capture Actions

Example AutoHotkey Script for Cloud Upload

#NoEnv
SendMode Input
F12::
; Capture using ShareX (silent mode)
Run, "C:\Program Files\ShareX\ShareX.exe" -capture -output "C:\Screenshots\%A_YYYYMMDD_HHMMSS%.png"

import os

def capture_and_ocr(output_dir="ocr_output"):
img = ImageGrab.grab()
img.save(os.path.join(output_dir, "screenshot.png"))
text = pytesseract.image_to_string(img)
with open(os.path.join(output_dir, "extracted_text.txt"), "w") as f:
f.write(text)
print("OCR complete. Text saved to:", os.path.join(output_dir, "extracted_text.txt"))

capture_and_ocr()

3. Bind Button to Script
Use AutoHotkey to execute the script when the Lenovo button is pressed:

F16::Run python C:\path\to\ocr_script.py, , Min

Replace `F16` with the detected keycode for the Lenovo screenshot button (verify via AutoHotkey’s `SendMode Input`).

Optimizations:


34. Region Selection: Modify the script to capture a specific window or monitor using `ImageGrab.grab(bbox=(x1, y1, x2, y2))`.

36. Performance: Pre-load Tesseract in memory to reduce startup latency.

Logging Button Presses for Usage Analytics

Tracking screenshot button presses provides insights into user behavior, software testing, or accessibility audits. Python or PowerShell scripts can log timestamps, active applications, and system metrics to a structured file.

PowerShell Logging Script

$logFile = "C:\Logs\ScreenshotButtonLog.csv"
$header = "Timestamp,ActiveWindow,ProcessName,CPUUsage"
if (!(Test-Path $logFile)) { $header | Out-File $logFile }

Register-HotKey -Key F16 -Action {
$timestamp = Get-Date -Format "yyyy-MM-dd HH:mm:ss"
$activeWindow = (Get-Process -Id (Get-WmiObject Win32_Process | Where-Object { $_.GetOwner().User -eq $env:USERNAME }).Id).MainWindowTitle
$processName = (Get-WmiObject Win32_Process | Where-Object { $_.GetOwner().User -eq $env:USERNAME }).Name
$cpuUsage = (Get-CimInstance Win32_PerfFormattedData_PerfProc_Process | Where-Object { $_.Name -eq $processName }).PercentProcessorTime

"$timestamp,$activeWindow,$processName,$cpuUsage" | Out-File $logFile -Append
}

Key Features:


37. Structured Output: CSV format for compatibility with tools like Excel or Pandas.
38. Contextual Data: Captures the active window, process name, and CPU usage at press time.
39. Scalability: Extend with additional metrics (e.g., memory usage, GPU load) via WMI queries.

Python Alternative (Cross-Platform)

import pyautogui
import psutil
