# 并击

并击双拼原理： 左手能控制23个声母，右手能控制24个韵母，把右手上左手没有的键，映射到左手。左手键映射到右手。 以下是一个示例。

```
chord_composer:
  # 字母表，包含用并击按键
  # 击键一律以字母表顺序排列
  alphabet: "aqzswxdecfrvgtbhynjumki,lo.;p',./"
  algebra:
    # - "xform/^,$/,/"
    # - "xform/^\.$/./"
    # 定义左手11键       
    - xform/^at(?![左右])/y左/
    - xform/^ar(?![左右])/u左/
    - xform/^ae(?![左右])/i左/
    - xform/^aw(?![左右])/o左/
    - xform/^qf(?![左右])/p左/
    - xform/^as(?![左右])/l左/
    - xform/^ad(?![左右])/k左/
    - xform/^af(?![左右])/j左/
    - xform/^ag(?![左右])/h左/
    - xform/^ac(?![左右])/m左/
    - xform/^av(?![左右])/n左/

    # 定义右手15键
    - xform/jp(?![左右])$/q右/
    - xform/jo(?![左右])$/w右/
    - xform/ji(?![左右])$/e右/
    - xform/ul(?![左右])$/r右/
    - xform/yl(?![左右])$/t右/
    - xform/l;(?![左右])$/s右/
    - xform/kl(?![左右])$/d右/
    - xform/jk(?![左右])$/f右/
    - xform/hl(?![左右])$/g右/    
    - xform/mk(?![左右])$/z右/
    - xform/nk(?![左右])$/x右/
    - xform/ml(?![左右])$/c右/
    - xform/nl(?![左右])$/v右/
    - xform/ni(?![左右])$/b右/
    - xform/;(?![左右])$/a右/
  # 并击完成后套用式样
  output_format:
    - "xform/^(.*)左/$1/"
    - "xform/^(.*)右$/$1/"
    - "xform/^(.*)左(.*)右$/$1$2/"
```

这样相当于左右手都能控制26个字母。（这段配置参考了星空键道） 我可以做到只用左手打字，也可以实现左右手并击，敲一次出一个字。因为我的字母顺序是左手字母在前，这样并击出来的字符就一定是声母在前。

例如：

地，本来就是左手声母，只需要并击d和i即可

皮，p在右手需要映射到左手，用qf，所以并击qf就出现p，并击qfi 就出现皮

么，m在右手，e在左手，正好相反。需要并击ac出m 并击ji出e，并击acji出么

我的方案优点是可串击可并击，可正常打字，可用单手。 我只是在正常双拼基础上，加了左右手映射。映射规则基本上就是镜像一下再加个字母，例如yuio镜像到左手分别是trew加上a，p是q加上f
