FKeys — 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
