[Space Cadet][space-cadet] Shift is a way to make it more convenient to input
|
|
parens - those `(` and `)` things -, symbols that a lot of programming languages
|
|
use frequently. If you are working with Lisp, you are using these all the time.
|
|
|
|
What it does, is that it turns your left and right `Shift` keys into parens if
|
|
you tap and release them, without pressing any other key while holding them.
|
|
Therefore, to input, say, `(print foo)`, you don't need to press `Shift`, hold
|
|
it, and press `9` to get a `(`, you simply press and release `Shift`, and
|
|
continue writing. You use it as if you had a dedicated key for parens!
|
|
|
|
But if you wish to write capital letters, you hold it, as usual, and you will
|
|
not see any parens when you release it. You can also hold it for a longer time,
|
|
and it still would act as a `Shift`, without the parens inserted on release:
|
|
this is useful when you want to augment some mouse action with `Shift`, to
|
|
select text, for example.

## Using the plugin
|
|
|
|
Using the plugin with its defaults is as simple as including the header, and
|
|
enabling the plugin:
|
|
|
|
```c++
|
|
#include <Kaleidoscope.h>
|
|
#include <Kaleidoscope-SpaceCadet.h>
|
|
|
|
void setup() {
|
|
USE_PLUGINS(&SpaceCadetShift);
|
|
|
|
Kaleidoscope.setup();
|
|
}
|
|
```
|
|
|
|
This assumes a US QWERTY layout on the host computer, and will use the `9` and
|
|
`0` keys for the left and right parens, respectively. To change these keys, use
|
|
the `.opening_paren` and `.closing_paren` properties outlined below.
|
|
|
|
## Plugin methods
|
|
|
|
The plugin provides the `SpaceCadetShift` object, with the following methods and
|
|
properties:
|
|
|
|
### `.opening_paren`
|
|
|
|
> Set this property to the key that - when shifted - will result in an opening paren.
|
|
>
|
|
> Defaults to `Key_9`.
|
|
|
|
### `.closing_paren`
|
|
|
|
> Set this property to the key that - when shifted - will result in a closing paren.
|
|
>
|
|
> Defaults to `Key_0`.
|
|
|
|
### `.time_out`
|
|
|
|
> Set this property to the number of milliseconds to wait before considering a
|
|
> held key in isolation as its secondary role. That is, we'd have to hold a
|
|
> `Shift` key this long, by itself, to trigger the `Shift` role in itself.
|
|
>
|
|
> Defaults to 1000.
