# Keyboard
Determining if `a` key is in the down state (pressed). This happens once each time the key is pressed:
```
if args.inputs.keyboard.key_down.a
puts 'The key is pressed'
end
```
Determining if a key is being held. This happens every tick while the key is held down:
```
if args.inputs.keyboard.key_held.a
puts 'The key is being held'
end
```
Determining if a key is in the down state or is being held:
```
if args.inputs.keyboard.a
puts 'The key is pressed or being held'
end
```
Determining if a key is in the up state (released). This happens once each time the key is released:
```
if args.inputs.keyboard.key_up.a
puts 'The key is released'
end
```
# Truthy Keys
You can access all triggered keys through `truthy_keys` on `keyboard`, `controller_one`, and `controller_two`.
This is how you would right all keys to a file. The game must be in the foreground and have focus for this data
to be recorded.
```
def tick args
[
[args.inputs.keyboard, :keyboard],
[args.inputs.controller_one, :controller_one],
[args.inputs.controller_two, :controller_two]
].each do |input, name|
if input.key_down.truthy_keys.length > 0
args.gtk.write_file("mygame/app/#{name}_key_down_#{args.state.tick_count}", input.key_down.truthy_keys.to_s)
end
end
end
```
# List of keys:
These are the character and associated properties that will
be set to true.
For example `A => :a, :shift` means that `args.inputs.keyboard.a`
would be true and so would `args.inputs.keyboard.shift`
(if both keys were being held or in the down state).
