## The new way: `SEND_STRING()` & `process_record_user`
Sometimes you just want a key to type out words or phrases. For the most common situations we've provided `SEND_STRING()`, which will type out your string for you. All ascii that is easily translated to a keycode is supported (eg `\n\t`).
Sometimes you just want a key to type out words or phrases. For the most common situations we've provided `SEND_STRING()`, which will type out your string (i.e. a sequence of characters) for you. All ASCII characters that are easily translated to a keycode are supported (e.g. `\n\t`).
For example:
For example, you could write in your `keymap.c`:
```c
enum custom_keycodes {
PRINT_TRUTH = SAFE_RANGE
MY_CUSTOM_MACRO = SAFE_RANGE
};
bool process_record_user(uint16_t keycode, keyrecord_t *record) {
if (record->event.pressed) {
switch(keycode) {
case PRINT_TRUTH:
case MY_CUSTOM_MACRO:
SEND_STRING("QMK is the best thing ever!");
return false; break;
}

### Tap/down/up
To activate this macro, assign the keycode `MY_CUSTOM_MACRO` to one of your keys in your keymap.
What happens here is this:
We first define a new custom keycode in the range not occupied by any other keycodes.
Then we use the `process_record_user` function, which is called whenever a key is pressed or released, to check if our custom keycode has been activated.
If yes, we send the string `"QMK is the best thing ever!"` to the computer via the `SEND_STRING` macro (this is a C preprocessor macro, not to be confused with QMK macros).
We return `false` to indicate to the caller that the key press we just processed need not be processed any further.
You might want to add more than one macro.
You can do that by adding another keycode and adding another case to the switch statement, like so:
```c
enum custom_keycodes {
MY_CUSTOM_MACRO = SAFE_RANGE,
MY_OTHER_MACRO
};
bool process_record_user(uint16_t keycode, keyrecord_t *record) {
if (record->event.pressed) {
switch(keycode) {
case MY_CUSTOM_MACRO:
SEND_STRING("QMK is the best thing ever!");
return false; break;
case MY_OTHER_MACRO:
SEND_STRING(SS_LCTRL("ac")); // selects all and copies
return false; break;
}
}
return true;
};
```
### TAP, DOWN and UP
You may want to use keys in your macros that you can't write down, such as `Ctrl` or `Home`.
You can send arbitary keycodes by wrapping them in:
* `SS_TAP()`
* `SS_DOWN()`
* `SS_UP()`
* `SS_TAP()` presses and releases a key.
* `SS_DOWN()` presses (but does not release) a key.
* `SS_UP()` releases a key.
For example:

* `SS_LGUI(string)`
* `SS_LALT(string)`
That can be used like this:
These press the respective modifier, send the supplied string and then release the modifier.
They can be used like this:
SEND_STRING(SS_LCTRL("a"));
Which would send LCTRL+a (LTRL down, a, LTRL up) - notice that they take strings (eg `"k"`), and not the `X_K` keycodes.
