Tap a key, but hold it *slightly* longer +and you get its shifted state. Viola! No shift key needeed! + +## Why Auto Shift? + +Many people suffer from various forms of RSI. A common cause is stretching your +fingers repeitively long distances. For us on the keyboard, the pinky does that +all too often when reaching for the shift key. Auto Shift looks to aliviate that +problem. + +## How does it work? + +When you tap a key, it stays depressed for a short period of time before it is +then released. This depressed time is a different length everyone. Auto Shift +defines a constant `AUTO_SHIFT_TIMEOUT` which is typically set to twice your +normal pressed state time. When you press a key, a timer starts and then stops +when you release the key. If the time depressed is greater than or equal to the +`AUTO_SHIFT_TIMEOUT` then a shifted version of the key is emitted. If the time +is less than the `AUTO_SHIFT_TIMEOUT` time, then the normal state is emitted. + +## Are there limitations to Auto Shift? + +Yes, unfortunately. + +1. Key repeat will cease to work. For example, before if you wanted 20 'a' + characters, you could press and hold the 'a' key for a second or two. This no + longer works with Auto Shift because it is timing your depressed time instead + of emitting a depressed key state to your operating system. +2. Auto Shift is disabled for any key press that is accompanied by one or more + modifiers. Thus, Ctrl+A that you hold for a really long time is not the same + as Ctrl+Shift+A. +3. You will have characters that are shifted 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 might 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. + +## How do I enable Auto Shift? + +Add to your `rules.mk` in the keymap folder: + + AUTO_SHIFT_ENABLE = YES + +If no `rules.mk` exists, you can create one. + +Then compile and install your new firmware with Auto Key enabled! That's it! + +## Configuring Auto Shift + +If desired, there is some configuration that can be done to change the +behavior of Auto Shift. This is done by setting various variables the +`config.h` file located in your keymap folder. + +If no `config.h` file exists, you can create one. A sample is + + #ifndef CONFIG_USER_H + #define CONFIG_USER_H + + #include "../../config.h" + + #define AUTO_SHIFT_TIMEOUT 150 + #define NO_AUTO_SHIFT_SPECIAL + + #endif + +### AUTO_SHIFT_TIMEOUT (value in ms) + +This controls how long you have to hold a key before you get the shifted state. +Obviously, this is different for everyone. For the common person a setting of +135 to 150 works great but one should start with a value of at least 175, which +is the default value. Then work down from there. The idea is to have as short +of a time required to get the shifted state without having false positives. + +Play with this value until things are perfect. Many find that all will work well +at a given value, but one or two keys will still emit the shifted state on +occassion. This is simply due to habit and holding some keys a little longer +than others. Once you find this value, work on tapping your problem keys a little +quicker than normal and you will be set. + +{% hint style='info' %} +Auto Shift has three special keys that can help you get this value right very +quick.

If you decide to increase the timeout, press the key you have mapped to + `KC_ASUP` and go back to step 1. +6. Once you are happy with your results, press the key you have mapped to + `KC_ASRP`. The keyboard will type by itself the value of your + `AUTO_SHIFT_TIMEOUT`. +7. Update `AUTO_SHIFT_TIMEOUT` in your `config.h` with the value reported. +8.
