+# Common Keymap Shortcuts
+
+Your keymap can include shortcuts to common operations, for example shifted keys. This page documents the functions that are available to you.
+
+People often define custom names using `#define`. For example:
+
+```c
+#define FN_CAPS LT(_FL, KC_CAPSLOCK)
+#define ALT_TAB LALT(KC_TAB)
+```
+
+This will allow you to use `FN_CAPS` and `ALT_TAB` in your `KEYMAP()`, keeping it more readable.
+
+### Limits of these aliases
+
+Currently, the keycodes able to used with these functions are limited to the [Basic Keycodes](keycodes.html), meaning you can't use keycodes like `KC_TILD`, or anything greater than 0xFF. For a full list of the keycodes able to be used see [Keycodes](keycodes.html).
+
+## Switching and toggling layers
+
+These functions allow you to activate layers in various ways.
+
+Care must be taken when switching layers, it's possible to lock yourself in a layer with no way to deactivate that layer (without unplugging your keyboard.) Always make sure that the layer you're switching into has the same key set to `KC_TRNS`.
+
+Layers stack on top of each other in numerical order, and as a result you can only activate a layer that is "above" your current layer. For example, on layer 2 you can't use `MO(1)`, the behavior will be undefined.
+
+* `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.
+* `LT(layer, kc)` - momentary switch to *layer* when held, and *kc* when tapped.
+* `TG(layer)` - toggles a layer on or off.
+* `TO(layer)` - Goes to a layer. This code is special, because it lets you go either up or down the stack -- just goes directly to the layer you want. So while other codes only let you go _up_ the stack (from layer 0 to layer 3, for example), `TO(2)` is going to get you to layer 2, no matter where you activate it from -- even if you're currently on layer 5. This gets activated on keydown (as soon as the key is pressed).
+* `TT(layer)` - Layer Tap-Toggle. If you hold the key down, the layer becomes active, and then deactivates when you let go. And if you tap it, the layer simply becomes active (toggles on). It needs 5 taps by default, but you can set it by defining `TAPPING_TOGGLE`, for example, `#define TAPPING_TOGGLE 2` for just two taps.
+
+## Modifier keys
+
+These functions allow you to combine a mod with a keycode. When pressed the keydown for the mod will be sent first, and then *kc* will be sent. When released the keyup for *kc* will be sent and then the mod will be sent.
+
+* `LSFT(kc)` or `S(kc)` - applies left Shift to *kc* (keycode)
+* `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*
+* `HYPR(kc)` - applies Hyper (all modifiers) to *kc*
+* `MEH(kc)` - applies Meh (all modifiers except Win/Cmd) to *kc*
+* `LCAG(kc)` - applies CtrlAltGui 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.
+
+## Shifted Keycodes
+
+The following shortcuts automatically add `LSFT()` to keycodes to get commonly used symbols.

+## Mod Tap
+
+`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.
+
+These are the values you can use for the `mod` in `MT()` and `OSM()`:
+
+ * MOD_LCTL
+ * MOD_LSFT
+ * MOD_LALT
+ * MOD_LGUI
+ * MOD_RCTL
+ * MOD_RSFT
+ * MOD_RALT
+ * MOD_RGUI
+ * MOD_HYPR
+ * MOD_MEH
+
+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. Note however, that you cannot mix right and left side modifiers.
+
+We've added shortcuts to make common modifier/tap (mod-tap) mappings more compact:
+
+ * `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
+ * `ALGR_T(kc)` - is AltGr 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. 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/)
+ * `LCAG_T(kc)` - is CtrlAltGui when held and *kc* when tapped
+ * `MEH_T(kc)` - is like Hyper, but not as cool -- does not include the Cmd/Win key, so just sends Alt+Ctrl+Shift.
+
+## One Shot Keys
+
+One shot keys are keys that remain active until the next key is pressed, and then are releasd. This allows you to type keyboard combinations without pressing more than one key at a time.
+
+For example, if you define a key as `OSM(MOD_LSFT)`, you can type a capital A character by first pressing and releasing shift, and then pressing and releasing A. Your computer will see the shift key being held the moment shift is pressed, and it will see the shift key being released immediately after A is released.
+
+One shot keys also work as normal modifiers. If you hold down a one shot key and type other keys, your one shot will be released immediately after you let go of the key.
+
+* `OSM(mod)` - Momentarily hold down *mod*. You must use the `MOD_*` keycodes as shown in [Mod Tap](#mod-tap), not the `KC_*` codes.
+* `OSL(layer)` - momentary switch to *layer*.
+
+
+## Permissive Hold
+
+As of [PR#1359](https://github.com/qmk/qmk_firmware/pull/1359/), there is a new `config.h` option:
+
+```
+#define PERMISSIVE_HOLD
+```
+
+This makes it easier for fast typists to use dual-function keys. Without this, if you let go of a held key inside the tapping term, it won't register.
+
+Example: (Tapping Term = 200ms)
+
+- SHFT_T(KC_A) Down
+- KC_X Down
+- KC_X Up
+- SHFT_T(KC_A) Up
+
+With defaults, if above is typed within tapping term, this will emit `ax`. With permissive hold, if above is typed within tapping term, this will emit `X` (so, Shift+X).

-# Quick Aliases To Common Actions
-
-Your keymap can include shortcuts to common operations (called "function actions" in tmk).
-
-These functions work the same way that their `ACTION_*` functions do - they're just quick aliases. To dig into all of the qmk `ACTION_*` functions, please see the [Keymap documentation](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.
-
-## Limits of these aliases
-
-Currently, the keycodes able to used with these functions are limited to the [Basic Keycodes](keycodes.html), meaning you can't use keycodes like `KC_TILD`, or anything greater than 0xFF. For a full list of the keycodes able to be used, [see this list](keycodes.html).

-# Switching and toggling layers
-
-`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.
-
-`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.
-
-`TO(layer)` - Goes to a layer. This code is special, because it lets you go either up or down the stack -- just goes directly to the layer you want. So while other codes only let you go _up_ the stack (from layer 0 to layer 3, for example), `TO(2)` is going to get you to layer 2, no matter where you activate it from -- even if you're currently on layer 5. This gets activated on keydown (as soon as the key is pressed).
-
-`TT(layer)` - Layer Tap-Toggle. If you hold the key down, the layer becomes active, and then deactivates when you let go. And if you tap it, the layer simply becomes active (toggles on). It needs 5 taps by default, but you can set it by defining `TAPPING_TOGGLE`, for example, `#define TAPPING_TOGGLE 1` for just one tap.

-# One Shot
-
-`OSM(mod)` - this is a "one shot" modifier. So let's say you have your left Shift key defined as `OSM(MOD_LSFT)`. Tap it, let go, and Shift is "on" -- but only for the next character you'll type. So to write "The", you don't need to hold down Shift -- you tap it, tap t, and move on with life. And if you hold down the left Shift key, it just works as a left Shift key, as you would expect (so you could type THE). There's also a magical, secret way to "lock" a modifier by tapping it multiple times. If you want to learn more about that, open an issue. :)
-
-`OSL(layer)` - momentary switch to *layer*, as a one-shot operation. So if you have a key that's defined as `OSL(1)`, and you tap that key, then only the very next keystroke would come from layer 1. You would drop back to layer zero immediately after that one keystroke. That's handy if you have a layer full of custom shortcuts -- for example, a dedicated key for closing a window. So you tap your one-shot layer mod, then tap that magic 'close window' key, and keep typing like a boss. Layer 1 would remain active as long as you hold that key down, too (so you can use it like a momentary toggle-layer key with extra powers).

-# Mod Tap
-
-`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.

- * MOD_LCTL
- * MOD_LSFT
- * MOD_LALT
- * MOD_LGUI
- * MOD_RCTL
- * MOD_RSFT
- * MOD_RALT
- * MOD_RGUI
- * MOD_HYPR
- * MOD_MEH
-
-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. Note however, that you cannot mix right and left side modifiers.
