# 中西文切換鍵的默認設置寫在 default.yaml 裏面
# 以下的 default.custom.yaml 在全局範圍重定義該組快速鍵
#
# 可用的按鍵有 Caps_Lock, Shift_L, Shift_R, Control_L, control_R
# Mac 系統上的鼠鬚管不能區分左、右，因此只有對 Shift_L, Control_L 的設定起作用
#
# 已輸入編碼時按切換鍵，可以進一步設定輸入法中西文切換的形式。
# 可選的臨時切換策略有三：
# inline_ascii 在輸入法的臨時西文編輯區內輸入字母、數字、符號、空格等，回車上屏後自動復位到中文
# commit_text 已輸入的候選文字上屏並切換至西文輸入模式
