So above you can see the stroke interval changed to 255ms between each keystroke, then a bunch of keys being typed, waits a while, then the macro ends.
Note: Using macros to have your keyboard send passwords for you is a bad idea.

### Additional keycode aliases for software-implemented layouts (Colemak, Dvorak, etc)
### Advanced macro functions
To get more control over the keys/actions your keyboard takes, the following functions are available to you in the `action_get_macro` function block:
#### `record->event.pressed`
This is a boolean value that can be tested to see if the switch is being pressed or released. An example of this is
```c
if (record->event.pressed) {
// on keydown
} else {
// on keyup
}
```
#### `record->tap.count`
The number taps that a certain key gets without interruption. This value can also be reset by assigning it `0`.
#### `register_code(<kc>);`
This sends the `<kc>` keydown event to the computer. Some examples would be `KC_ESC`, `KC_C`, `KC_4`, and even modifiers such as `KC_LSFT` and `KC_LGUI`.
#### `unregister_code(<kc>);`
Parallel to `register_code` function, this sends the `<kc>` keyup event to the computer. If you don't use this, the key will be held down until it's sent.
#### `layer_on(<n>);`
This will turn on the layer `<n>` - the higher layer number will always take priority. Make sure you have `KC_TRNS` for the key you're pressing on the layer you're switching to, or you'll get stick there unless you have another plan.
#### `layer_off(<n>);`
This will turn off the layer `<n>`.
#### `clear_keyboard();`
This will clear all mods and keys currently pressed.
#### `clear_mods();`
This will clear all mods currently pressed.
#### `clear_keyboard_but_mods();`
This will clear all keys besides the mods currently pressed.
#### Timer functionality
It's possible to start timers and read values for time-specific events - here's an example:
```c
static uint16_t key_timer;
key_timer = timer_read();
if (timer_elapsed(key_timer) < 100) {
// do something if less than 100ms have passed
} else {
// do something if 100ms or more have passed
}
```
It's best to declare the `static uint16_t start;` outside of the macro block (top of file, etc).
## Additional keycode aliases for software-implemented layouts (Colemak, Dvorak, etc)
Everything is assuming you're in Qwerty (in software) by default, but there is built-in support for using a Colemak or Dvorak layout by including this at the top of your keymap:
