Wait for key mode
Most of the time, games expect you to enter a phrased command. Sometimes, however, a game may request a single keypress from the keyboard. In this case, the input prompt also changes:
The checkmark on the right produces is the same as the enter key. The arrows translate to cursor keys and the keyboard symbol on the left brings up the onscreen keyboard (in case a game needs a letter or a number).
Please note that the buttons are provided by Text Fiction and not specified by the game. The game may react to them in any case it likes (including not at all).
For technical reasons, it is impossible to save while the game is in this mode. This includes autosaving. Should you happen to press the back button, then your game state will be lost.
