How do I pause the game, wait for a keystroke, change the color of the screen or letters, or make major changes to the status line?
Several extensions come included with Inform to help with these sorts of things. To find out how to use them, look in the Installed Extensions section and then read their individual documentation. Basic Screen Effects and Glulx Text Effects handle many kinds of lettering issues; the Unicode extensions provide support for a wide range of glyphs; Punctuation Removal and Case Management do small but sometimes useful tasks with the player’s input and game output. There is also a menu system and a sample help menu extension to go with it, if you want to offer your player a menu of instructions for playing IF.
