-* `RSFT(kc)` - applies right shift to *kc*
-* `LCTL(kc)` - applies left control to *kc*
-* `RCTL(kc)` - applies right control to *kc*

-* `RALT(kc)` - applies right alt to *kc*
-* `LGUI(kc)` - applies left gui (command/win) to *kc*
-* `RGUI(kc)` - applies right gui (command/win) to *kc*
+Your keymap can include shortcuts to common operations (called "function actions" in tmk).
 
-You can also use more than one, like this:
+### Switching and toggling layers
 
-    LALT(LGUI(KC_ESC))
+`MO(layer)` - momentary switch to *layer*. As soon as you let go of the key, the layer is deactivated and you pop back out to the previous layer. When you apply this to a key, that same key must be set as `KC_TRNS` on the destination layer. Otherwise, you won't make it back to the original layer when you release the key (and you'll get a keycode sent). You can only switch to layers *above* your current layer. If you're on layer 0 and you use `MO(1)`, that will switch to layer 1 just fine. But if you include `MO(3)` on layer 5, that won't do anything for you -- because layer 3 is lower than layer 5 on the stack.
 
-The following shortcuts automatically add `LSFT()` to keycodes to get commonly used symbols. Their long names (see `quantum/keymap_common.h`) are also availble.
+`LT(layer, kc)` - momentary switch to *layer* when held, and *kc* when tapped. Like `MO()`, this only works upwards in the layer stack (`layer` must be higher than the current layer).
+
+`TG(layer)` - toggles a layer on or off. As with `MO()`, you should set this key as `KC_TRNS` in the destination layer so that tapping it again actually toggles back to the original layer. Only works upwards in the layer stack.
+
+### Fun with modifier keys
+
+* `LSFT(kc)` - applies left Shift to *kc* (keycode) - `S(kc)` is an alias
+* `RSFT(kc)` - applies right Shift to *kc*
+* `LCTL(kc)` - applies left Control to *kc*
+* `RCTL(kc)` - applies right Control to *kc*
+* `LALT(kc)` - applies left Alt to *kc*
+* `RALT(kc)` - applies right Alt to *kc*
+* `LGUI(kc)` - applies left GUI (command/win) to *kc*
+* `RGUI(kc)` - applies right GUI (command/win) to *kc*
+
+You can also chain these, like this:
+
+    LALT(LCTL(KC_DEL)) -- this makes a key that sends Alt, Control, and Delete in a single keypress.
+
+The following shortcuts automatically add `LSFT()` to keycodes to get commonly used symbols. Their long names are also available and documented in `/quantum/keymap_common.h`.

-### Function shortcuts
+`MT(mod, kc)` - is *mod* (modifier key - MOD_LCTL, MOD_LSFT) when held, and *kc* when tapped. In other words, you can have a key that sends Esc (or the letter O or whatever) when you tap it, but works as a Control key or a Shift key when you hold it down. 
 
-Instead of using `FNx`, you can use `F(x)` - the benefit here is being able to use more than 32 function layers (up to 4096), if you happen to need them.
+These are the values you can use for the `mod` in `MT()` (right-hand modifiers are not available):
 
-There are also keycode shortcuts for common actions:
+  * MOD_LCTL
+  * MOD_LSFT
+  * MOD_LALT
+  * MOD_LGUI
+
+These can also be combined like `MOD_LCTL | MOD_LSFT` e.g. `MT(MOD_LCTL | MOD_LSFT, KC_ESC)` which would activate Control and Shift when held, and send Escape when tapped.
+
+We've added shortcuts to make common modifier/tap (mod-tap) mappings more compact:
 
-* `MO(layer)` - momentary switch to *layer*
-* `DF(layer)` - sets default layer to *layer*
-* `TG(layer)` - toggle between the current layer and *layer*
-* `MT(mod, kc)` - is *mod* when held, and *kc* when tapped
   * `CTL_T(kc)` - is LCTL when held and *kc* when tapped 
   * `SFT_T(kc)` - is LSFT when held and *kc* when tapped 
   * `ALT_T(kc)` - is LALT when held and *kc* when tapped 
   * `GUI_T(kc)` - is LGUI when held and *kc* when tapped 
-  * `ALL_T(kc)` - is Hyper (all mods) when held and *kc* when tapped 
-* `LT(layer, kc)` - momentary switch to *layer* when held, and *kc* when tapped
+  * `ALL_T(kc)` - is Hyper (all mods) when held and *kc* when tapped. To read more about what you can do with a Hyper key, see [this blog post by Brett Terpstra](http://brettterpstra.com/2012/12/08/a-useful-caps-lock-key/)
 
-These functions work the same way that their `ACTION_*` functions do, and will require KC_TRNS on the layer being switched to - check out the default keymap for an example.
+### Temporarily setting the default layer 
 
-### Additional keycodes for software-implemented layouts (Colemak, Dvorak, etc)
+`DF(layer)` - sets default layer to *layer*. The default layer is the one at the "bottom" of the layer stack - the ultimate fallback layer. This currently does not persist over power loss. When you plug the keyboard back in, layer 0 will always be the default. It is theoretically possible to work around that, but that's not what `DF` does.
+
+### Remember: These are just aliases
+
+These functions work the same way that their `ACTION_*` functions do - they're just quick aliases. To dig into all of the tmk ACTION_* functions, please see the [TMK documentation](https://github.com/jackhumbert/qmk_firmware/blob/master/tmk_core/doc/keymap.md#2-action).
+
+Instead of using `FNx` when defining `ACTION_*` functions, you can use `F(x)` - the benefit here is being able to use more than 32 function actions (up to 4096), if you happen to need them.
+
+## Macro shortcuts: Send a whole string when pressing just one key
+
+Instead of using the `ACTION_MACRO` function, you can simply use `M(n)` to access macro *n* - *n* will get passed into the `action_get_macro` as the `id`, and you can use a switch statement to trigger it. This gets called on the keydown and keyup, so you'll need to use an if statement testing `record->event.pressed` (see keymaps/default.c).
+
+```c
+const macro_t *action_get_macro(keyrecord_t *record, uint8_t id, uint8_t opt) // this is the function signature -- just copy/paste it into your keymap file as it is.
+{
+  switch(id) {
+    case 0: // this would trigger when you hit a key mapped as M(0)
+      if (record->event.pressed) {
+        return MACRO( I(255), T(H), T(E), T(L), T(L), W(255), T(O), END  ); // this sends the string 'hello' when the macro executes
+      } 
+      break;
+  }
+  return MACRO_NONE;
+};
+```
+A macro can include the following commands:
+
+* I() change interval of stroke in milliseconds.
+* D() press key.
+* U() release key.
+* T() type key(press and release).
+* W() wait (milliseconds).
+* END end mark.
+
+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)
 
 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:
 
-     #include "keymap_<layout>.h"

 You can currently send 4 hex digits with your OS-specific modifier key (RALT for OSX with the "Unicode Hex Input" layout) - this is currently limited to supporting one OS at a time, and requires a recompile for switching. 8 digit hex codes are being worked on. The keycode function is `UC(n)`, where *n* is a 4 digit hexidecimal. Enable from the Makefile.
