重新映射键（包括修饰符）

我在 Ubuntu 18.04 上使用替代的德语键盘布局：

~$ setxkbmap de koy

现在我想交换三个键 (Mod3 → f → ß → Mod3)，如图所示： 交换三把钥匙

这是这些键的键码：

~$ xmodmap -pke | grep -E 'keycode  (33|48|51)'
keycode  33 = ssharp U1E9E ssharp U1E9E ampersand Greek_finalsmallsigma KP_Add KP_Add jot NoSymbol ampersand Greek_finalsmallsigma KP_Add KP_Add jot
keycode  48 = f F f F at Greek_phi period KP_Decimal Greek_PHI NoSymbol at Greek_phi period KP_Decimal Greek_PHI
keycode  51 = ISO_Level3_Shift NoSymbol ISO_Level3_Shift

Q1：为什么 f 键和 ß 键有 15 列？/usr/share/X11/xkb/symbols/de只定义了8列！

我可以使用这些 xmodmap 命令交换密钥：

~$ xmodmap -e "keycode  51 = ssharp U1E9E ssharp U1E9E ampersand Greek_finalsmallsigma KP_Add KP_Add jot NoSymbol ampersand Greek_finalsmallsigma KP_Add KP_Add jot"
~$ xmodmap -e "keycode  33 = f F f F at Greek_phi period KP_Decimal Greek_PHI NoSymbol at Greek_phi period KP_Decimal Greek_PHI"
~$ xmodmap -e "keycode  48 = ISO_Level3_Shift NoSymbol ISO_Level3_Shift"

现在钥匙已经交换了，但是……

  • ß (ssharp) 键ß在所有级别上返回！预期（与交换前一样）：ß ẞ & + ς ∘
  • 键 48（以前的 f 键）除与其他修饰符一起使用时外，其作用与 Mod3 相同：Shift+Mod3+a 应该给出一个，α但现在给出一个A。

只是再次检查：

~$ xmodmap -pke | grep -E 'keycode  (33|48|51)'
keycode  33 = f F f F ampersand Greek_phi KP_Add KP_Add Greek_PHI NoSymbol ampersand Greek_phi KP_Add KP_Add Greek_PHI NoSymbol f F ampersand Greek_phi KP_Add KP_Add Greek_PHI NoSymbol f F ampersand Greek_phi KP_Add KP_Add Greek_PHI
keycode  48 = ISO_Level3_Shift NoSymbol ISO_Level3_Shift NoSymbol NoSymbol NoSymbol NoSymbol NoSymbol NoSymbol NoSymbol NoSymbol NoSymbol NoSymbol NoSymbol NoSymbol NoSymbol ISO_Level3_Shift NoSymbol NoSymbol NoSymbol NoSymbol NoSymbol NoSymbol NoSymbol ISO_Level3_Shift
keycode  51 = ssharp NoSymbol ssharp U1E9E at Greek_finalsmallsigma period KP_Decimal

键码 48 和 51 不是我设置的。

Q2：出了什么问题？

在 StackExchange 上的其他一些问题中，人们表示在更改修饰符之前删除或清除修饰符很重要。但这总是失败：

~$ xmodmap -pm
xmodmap:  up to 3 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x32),  Shift_R (0x3e)
lock        Shift_L (0x32)
control     Control_L (0x25),  Control_R (0x69)
mod1        Alt_L (0x40),  Meta_L (0xcd)
mod2        BadKey (0xcf)
mod3        ISO_Level5_Shift (0xcb)
mod4        Super_L (0x85),  Super_R (0x86),  Super_L (0xce)
mod5        ISO_Level3_Shift (0x5c)

~$ xmodmap -e "remove mod5 = ISO_Level3_Shift"
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  118 (X_SetModifierMapping)
  Value in failed request:  0x17
  Serial number of failed request:  11
  Current serial number in output stream:  11

~$ xmodmap -e "clear mod5"
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  118 (X_SetModifierMapping)
  Value in failed request:  0x17
  Serial number of failed request:  8
  Current serial number in output stream:  8

Q3：这些错误是什么意思？
