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
- @{string}: The event name.
- @{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
