FKeys by RailwayMealCalculator

FKeys puts a floating F1-F12 button bar on CATS terminal pages so you
can work the terminal without a physical keyboard. It is built for
phone, tablet and Chromebook users who do not have function keys.

The F-key tools work on their own with no account and no sign-in.

Features
• F1-F12 buttons that press the terminal's own controls, not simulated
keystrokes
• An OK button that follows the terminal's own OK button on every screen
• Arrow buttons for moving between input fields
• Tappable menu options, so you can tap "001 ENGINE SERVICE" instead of
typing 001 and pressing OK
• Tappable F-key labels, so you can tap "F3=EXIT" to fire F3
• A sign-in button on the login screen, using credentials you save on
your own device
• A settings page behind the gear

With a TicketForge account
Sign in to turn on timeslip tracking, so you can keep track of your
hours worked and your pay. It is a tool you run, not something that runs
on its own. You tell it which year to pull and you press Start, and it
reads your own timeslips off the terminal into your account. It also
keeps the terminal screen behind each ticket, so your records hold the
original screen rather than a retyped copy.

Your data
Without an account, nothing from your terminal and nothing you type
leaves your device. The add-on checks ticketforge.ca for its own updates
and reports whether an update installed, and that is all.

Signed in, your own timeslips go to your own account and nowhere else.
You can also let terminal screens be shared so faults can be diagnosed.
Crew names, nine digit employee numbers and anything typed into a field
are removed on your own machine first, the sign-in screen is never
captured, and switching it off in your profile discards anything already
waiting.
