module: [kind=event] key_up see: keys For a lookup table of the given keys.

Fired whenever a key is released (or the terminal is closed while a key was being pressed).

This event returns a numerical "key code" (for instance, F1 is 290). This value may vary between versions and so it is recommended to use the constants in the [keys] API rather than hard coding numeric values.

Return values

  1. [string]: The event name.
  2. [number]: The numerical key value of the key pressed.

Example

Prints each key released on the keyboard whenever a [key_up] event is fired.

while true do
  local event, key = os.pullEvent("key_up")
  local name = keys.getName(key) or "unknown key"
  print(name .. " was released.")
end
