+### Advanced Macros
+
+In addition to the `process_record_user()` function, is the `post_process_record_user()` function. This runs after `process_record` and can be used to do things after a keystroke has been sent.  This is useful if you want to have a key pressed before and released after a normal key, for instance. 
+
+In this example, we modify most normal keypresses so that `F22` is pressed before the keystroke is normally sent, and release it __only after__ it's been released.
+
+```c
+static uint8_t f22_tracker;
+
+bool process_record_user(uint16_t keycode, keyrecord_t *record) {
+  switch (keycode) {
+    case KC_A ... KC_F21: //notice how it skips over F22
+    case KC_F23 ... KC_EXSEL: //exsel is the last one before the modifier keys
+      if (record->event.pressed) {
+        register_code(KC_F22); //this means to send F22 down
+        f22_tracker++;
+        register_code(keycode);
+        return false;
+      }
+      break;
+  }
+  return true;
+}
+
+void post_process_record_user(uint16_t keycode, keyrecord_t *record) {
+  switch (keycode) {
+    case KC_A ... KC_F21: //notice how it skips over F22
+    case KC_F23 ... KC_EXSEL: //exsel is the last one before the modifier keys
+      if (!record->event.pressed) {
+        f22_tracker--;
+        if (!f22_tracker) {
+            unregister_code(KC_F22); //this means to send F22 up
+        }
+      }
+      break;
+  }
+}
+```

+# Word Per Minute (WPM) Calculcation
+
+The WPM feature uses time between keystrokes to compute a rolling average words
+per minute rate and makes this available for various uses.
+
+Enable the WPM system by adding this to your `rules.mk`:
+
+    WPM_ENABLE = yes
+
+For split keyboards using soft serial, the computed WPM
+score will be available on the master AND slave half.
+
+## Public Functions
+
+`uint8_t get_current_wpm(void);`
+This function returns the current WPM as an unsigned integer.
+
+
+## Customized keys for WPM calc
+
+By default, the WPM score only includes letters, numbers, space and some
+punctuation.  If you want to change the set of characters considered as part of
+the WPM calculation, you can implement `wpm_keycode_user(uint16_t keycode)`
+and return true for any characters you would like included in the calculation,
+or false to not count that particular keycode.
