# Auto Shift: Why do we need a shift key?
|
||||
|
||||
Tap a key and you get its character. 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. See "Auto Shift Setup" for more details!
|
||||
{% endhint %}
|
||||
|
||||
### NO_AUTO_SHIFT_SPECIAL (simple define)
|
||||
|
||||
Do not Auto Shift special keys, which include -_, =+, [{, ]}, ;:, '", ,<, .>,
|
||||
and /?
|
||||
|
||||
### NO_AUTO_SHIFT_NUMERIC (simple define)
|
||||
|
||||
Do not Auto Shift numeric keys, zero through nine.
|
||||
|
||||
### NO_AUTO_SHIFT_ALPHA (simple define)
|
||||
|
||||
Do not Auto Shift alpha characters, which include A through Z.
|
||||
|
||||
## Using Auto Shift Setup
|
||||
|
||||
This will enable you to define three keys temporailiy to increase, decrease and report your `AUTO_SHIFT_TIMEOUT`.
|
||||
|
||||
### Setup
|
||||
|
||||
Map three keys temporarily in your keymap:
|
||||
|
||||
| Key Name | Description |
|
||||
|----------|-----------------------------------------------------|
|
||||
| KC_ASDN | Lower the Auto Shift timeout variable (down) |
|
||||
| KC_ASUP | Raise the Auto Shift timeout variable (up) |
|
||||
| KC_ASRP | Report your current Auto Shift timeout value |
|
||||
|
||||
Compile and upload your new firmware.
|
||||
|
||||
### Use
|
||||
|
||||
It is important to note that during these tests, you should be typing
|
||||
completely normal and with no intention of shifted keys.
|
||||
|
||||
1. Type multiple sentences of alphabetical letters.
|
||||
2. Observe any upper case letters.
|
||||
3. If there are none, press the key you have mapped to `KC_ASDN` to decrease
|
||||
time Auto Shift timeout value and go back to step 1.
|
||||
4. If there are some upper case letters, decide if you need to work on tapping
|
||||
those keys with less down time, or if you need to increase the timeout.
|
||||
5. 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. Remove `AUTO_SHIFT_SETUP` from your `config.h`.
|
||||
9. Remove the key bindings `KC_ASDN`, `KC_ASUP` and `KC_ASRP`.
|
||||
10. Compile and upload your new firmware.
|
||||
|
||||
#### An example run
|
||||
|
||||
\'\'\'
|
||||
hello world. my name is john doe. i am a computer programmer playing with
|
||||

|
||||
|
||||

||||

||||

|
||||

|
||||
|
||||
[PRESS KC_ASUP a few times]
|
||||
|
||||
hello world. my name is john Doe. i am a computer programmer play with

|
||||
[PRESS KC_ASRP]
|
||||
|
||||
115
|
||||
\'\'\'
|
||||
|
||||
The keyboard typed `115` which represents your current `AUTO_SHIFT_TIMEOUT`
|
||||
value. You are now set! Practice on the *D* key a little bit that showed up
|
||||
in the testing and you'll be golden.
