• fgl_dialog_setcurrline() displays the specified row of the program array at the specified line of the screen array
• fgl_getkey() waits for a key to be pressed and returns the integer code of the keystroke
• fgl_key_queue() pushes the specified key value into the key queue
• fgl_keyname() returns the key name by its value
• fgl_keyval() returns the integer code of a logical or physical key
• fgl_lastkey() returns the integer code for the last key received at runtime
