Hot Keys

 are keys on the keyboard that preform certain actions in BTD4, BTD5, and Bloons Monkey City. Pressing them will instantly place the chosen tower on your mouse ready for placement or it will perform another action listed below. Sometimes the player has to click on a Hot Key twice for it to register with the game (this used to happen in BTD5, hot keys can now only be pressed once, but this still applies to BTD5 Deluxe, even in the latest version). Hotkeys allow you to shortcut controls while you are playing the game. The keys in Bloons Monkey City are the same as the ones in Bloons Tower Defense 5.
