the game controls for Transport Empire were discussed. The Design Document doesn't mention them anywhere though.
Transport Empire can be played with a keyboard and any mouse with at least 2 buttons. Mice with a scroll wheel will have added functionality to the mouse, i.e. zooming in/out can be assigned to scrolling the mousewheel up or down. The keyboard is primarily required for text input. Function keys (F1-F12) and Ctrl, Alt and Shift keys are available for quick selection of menus and or they enhance mouse functionality. Free keyboard characters can be mapped as shortcuts for frequently used actions, i.e. choosing track type, building a signal etc. Players are free to map the keyboard characters to their own preferences.
should we already think of game menus that we will need and how those menus can be called?
