## Are There Limitations to Auto Shift?
Yes, unfortunately.
-You will have characters that are shifted when you did not intend on shifting, and
-other characters you wanted shifted, but were not. This simply comes down to
-practice. As we get in a hurry, we think we have hit the key long enough for a
-shifted version, but we did not. On the other hand, we may think we are tapping
-the keys, but really we have held it for a little longer than anticipated.
-
-Additionally, with keyrepeat the desired shift state can get mixed up. It will
-always 'belong' to the last key pressed. For example, keyrepeating a capital
-and then tapping something lowercase (whether or not it's an Auto Shift key)
-will result in the capital's *key* still being held, but shift not.

?> Auto Shift has three special keys that can help you get this value right very quick. See "Auto Shift Setup" for more details!
+For more granular control of this feature, you can add the following to your `config.h`:
+
+```c
+#define AUTO_SHIFT_TIMEOUT_PER_KEY
+```
+
+You can then add the following function to your keymap:
+
+```c
+uint16_t get_autoshift_timeout(uint16_t keycode, keyrecord_t *record) {
+ switch(keycode) {
+ case AUTO_SHIFT_NUMERIC:
+ return 2 * get_generic_autoshift_timeout();

+ return get_generic_autoshift_timeout() + 50;
+ case AUTO_SHIFT_ALPHA:
+ default:
+ return get_generic_autoshift_timeout();
+ }
+}
+```
+
+Note that you cannot override individual keys that are in one of those groups
+if you are using them; trying to add a case for `KC_A` in the above example will
+not compile as `AUTO_SHIFT_ALPHA` is there. A possible solution is a second switch
+above to handle individual keys with no default case and only referencing the
+groups in the below fallback switch.

+## Custom Shifted Values
+
+Especially on small keyboards, the default shifted value for many keys is not
+optimal. To provide more customizability, there are two user-definable
+functions, `autoshift_press/release_user`. These register or unregister the
+correct value for the passed key. Below is an example adding period to Auto
+Shift and making its shifted value exclamation point. Make sure to use weak
+mods - setting real would make any keys following it use their shifted values
+as if you were holding the key. Clearing of modifiers is handled by Auto Shift,
+and the OS-sent shift value if keyrepeating multiple keys is always that of
+the last key pressed (whether or not it's an Auto Shift key).
+
+You can also have non-shifted keys for the shifted values (or even no shifted
+value), just don't set a shift modifier!
+

+
+## Retro Shift
+
+Holding and releasing a Tap Hold key without pressing another key will ordinarily
+result in only the hold. With `retro shift` enabled this action will instead
+produce a shifted version of the tap keycode on release.
+
+It does not require [Retro Tapping](tap_hold.md#retro-tapping) to be enabled, and
+if both are enabled the state of `retro tapping` will only apply if the tap keycode
+is not matched by Auto Shift. `RETRO_TAPPING_PER_KEY` and its corresponding
+function, however, are checked before `retro shift` is applied.
+
+To enable `retro shift`, add the following to your `config.h`:
+
+```c
+#define RETRO_SHIFT
+```
+
+If `RETRO_SHIFT` is defined to a value, hold times greater than that value will
+not produce a tap on release for Mod Taps, and instead triggers the hold action.
+This enables modifiers to be held for combining with mouse clicks without
+generating taps on release. For example:
+
+```c
+#define RETRO_SHIFT 500
+```
+
+This value (if set) must be greater than one's `TAPPING_TERM`, as the key press
+must be designated as a 'hold' by `process_tapping` before we send the modifier.
+There is no such limitation in regards to `AUTO_SHIFT_TIMEOUT` for normal keys.
+
+### Retro Shift and Tap Hold Configurations
+
+Tap Hold Configurations work a little differently when using Retro Shift.
+Referencing `TAPPING_TERM` makes little sense, as holding longer would result in
+shifting one of the keys.
+
+`IGNORE_MOD_TAP_INTERRUPT` changes *only* rolling from a mod tap (releasing it
+first), sending both keys instead of the modifier on the second. Its effects on
+nested presses are ignored.
+
+As nested taps were changed to act as though `PERMISSIVE_HOLD` is set unless only
+`IGNORE_MOD_TAP_INTERRUPT` is (outside of Retro Shift), and Retro Shift ignores
+`IGNORE_MOD_TAP_INTERRUPT`, `PERMISSIVE_HOLD` has no effect on Mod Taps.
+
+Nested taps will *always* act as though the `TAPPING_TERM` was exceeded for both
+Mod and Layer Tap keys.
+
## Using Auto Shift Setup
This will enable you to define three keys temporarily to increase, decrease and report your `AUTO_SHIFT_TIMEOUT`.

+### Retro Shift
+
+[Auto Shift,](feature_auto_shift.md) has its own version of `retro tapping` called `retro shift`. It is extremely similar to `retro tapping`, but holding the key past `AUTO_SHIFT_TIMEOUT` results in the value it sends being shifted. Other configurations also affect it differently; see [here](feature_auto_shift.md#retro-shift) for more information.

## Why do we include the key record for the per key functions?
One thing that you may notice is that we include the key record for all of the "per key" functions, and may be wondering why we do that.
