FKeys 作者： RailwayMealCalculator

FKeys injects a floating F1-F12 button bar into PSTS/Jacada mainframe terminal pages so you can use the mainframe without a physical keyboard. Perfect for Chromebook, tablet, and phone users who don't have function keys.

Features
• F1-F12 buttons that click the real Jacada DOM elements (not synthetic keystrokes)
• OK button anchored to the top edge of the native Jacada OK button on every screen
• D-pad arrow buttons to navigate between input fields
• Clickable numbered menu option overlays - tap "001 ENGINE SERVICE" instead of typing 001 + OK
• Clickable F-key label overlays - tap "F3=EXIT" to fire F3
• Auto-login button on the PSTS login screen (uses credentials you save locally)
• VPN portal helper that auto-fills Ivanti and SecureAuth login pages
• Settings gear opens the options page

Privacy
FKeys makes no network requests. Any credentials you enter on the options page (employee ID, PSTS terminal password, VPN password) are stored only in your browser's extension storage and are used only to auto-fill the respective login fields on your behalf.

This extension is a standalone fork of the "PSTS Scraper for MealCalc" extension with all ticket scraping and all server communication removed.
