## Design

This dictionary is inspired by and can essentially be seen as a combination of

[Emily's Modifiers](https://github.com/EPLHREU/emily-modifiers) and 

[Achim Siebert's Left Hand Modifier Keys](http://www.openstenoproject.org/stenodict/dictionaries/lh_modifier_keys.html).

Essentially, it allows every shortcut to be typed in two strokes and using only

the left hand. As such, only the following keys are used:

![Key layout](img/all.png)

In some combinations, the asterisk key is used. This requires the asterisk key

to be pressed using the left hand, which should be fine on most hobbyist writers

but may be a problem on some professional writers.

## Modifiers

The first of the two strokes in each combination is used to specify the modifier

keys that should be pressed. It is also possible to not press any modifier keys,

since some applications have shortcuts that are activated by just a single

keypress.

### Single modifier keys

Patterns for single modifier keys.

| Stroke             | Modifier                | Explanation                          |

| ------------------ | ----------------------- | ------------------------------------ |

| ![](img/ctrl.png)  | Control                 | **C**ontro**L**                      |

| ![](img/alt.png)   | Alt                     | **ALT** (reversed)                   |

| ![](img/shift.png) | Shift                   | **SH**ift                            |

| ![](img/super.png) | Super (Windows/Command) | Purely positional, no phonetic basis |

### Modifier key combinations

Modifier key combinations are made by stacking the chords for individual

modifier keys on top of each other, with three exceptions:

- The Ctrl + Alt + Super combination is given `TKPWHRAO`, with an additional `O`

due to a conflict with `TKPWHRA` for Alt + Super.

- The Ctrl + Shift + Super combination is given `SKPWHRO`, with an additional

`O` due to a conflict with `SKPWHR` for Shift + Super.

- The Ctrl + Alt + Shift + Super combination is given `STKPWHRAO`, with an

additional `O` due to a conflict with `STKPWHRA` for Alt + Shift + Super.

| Stroke                            | Modifiers                  |

| --------------------------------- | -------------------------- |

| ![](img/alt-shift.png)            | Alt + Shift                |

| ![](img/ctrl-alt.png)             | Ctrl + Alt                 |

| ![](img/ctrl-shift.png)           | Ctrl + Shift               |

| ![](img/ctrl-alt-shift.png)       | Ctrl + Alt + Shift         |

| ![](img/ctrl-super.png)           | Ctrl + Super               |

| ![](img/alt-super.png)            | Alt + Super                |

| ![](img/ctrl-alt-super.png)       | Ctrl + Alt + Super         |

| ![](img/shift-super.png)          | Shift + Super              |

| ![](img/ctrl-shift-super.png)     | Ctrl + Shift + Super       |

| ![](img/alt-shift-super.png)      | Alt + Shift + Super        |

| ![](img/ctrl-alt-shift-super.png) | Ctrl + Alt + Shift + Super |

The pattern for no modifier keys is `TKPWHR`. This presses a key specified in

the second stroke without any additional modifier keys.

| Stroke                    | Modifiers |

| ------------------------- | --------- |

| ![](img/no-modifiers.png) | None      |

## Keys

The second of the two strokes in each combination specifies what key to press

along with the modifiers (if any) selected above.

### Letters

The patterns for letter keys are the same as the fingerspelling pattern for that

letter (without the asterisk), except for E, I, and U which have been given

special patterns so they fit on the left hand. (Using `E`, `EU`, and `U` for E,

I, and U still work, but are not shown below.)

| ![](img/down.png)  | Down  |

| ![](img/left.png)  | Left  |

to act as page up, page down, home, and end.

| ------------------ | --------- |

| ![](img/prior.png) | Page Up   |

keys included.
