我在 Centos 6.9 机器上运行 emacs 26.1,通过 TightVNC 服务器向在 Mac OS X 10.14.2 上运行的客户端显示。为了让事情变得棘手,我还使用了德沃夏克键盘布局。
当我在 Mac 上运行 emacs 时,一切都运行良好。我的 Mac 键盘是Apple Magic Keyboard with Numeric Keypad (Wireless, Rechargable) (US English) - Silver
.如果我option
按左侧或右侧的 ,它就会按预期工作并meta
在 Emacs 中生成。如果我command
按左侧或右侧的 ,它也会按需要工作并且也会meta
在 Emacs 中生成。我相信这是通过以下方法完成的(这并不能解决我在 Linux 上的问题):
(setq mac-option-modifier 'meta)
(setq mac-command-modifier 'meta)
现在,我尝试通过 TigerVNC 从 Mac 连接到也运行 Emacs 的 Linux 计算机。在 Centos 6.9 机器上,我必须禁用 Dvorok 键盘布局首选项,因为它会扰乱 Mac 键盘的输入,我认为执行转换两次,一次在我的 Mac 上,第二次在 Linux 机器上。
但是,修饰键无法按预期工作。以下是我尝试以M-x
各种方式生成时得到的结果:
- 左选项-x => 不正确:
≈
- 左命令-x => 正确:
M-x
- 右选项-x => 不正确:
≈
- 右命令-x => 错误:
s-x
我跑了xmodmap -pm
:
xmodmap: up to 4 keys per modifier, (keycodes in parentheses):
shift Shift_L (0x32), Shift_R (0x3e)
lock Caps_Lock (0x42)
control Control_L (0x25), Control_R (0x69)
mod1 Alt_L (0x40), Alt_R (0x6c), Meta_L (0xcd)
mod2 Num_Lock (0x4d)
mod3
mod4 Super_L (0x85), Super_R (0x86), Super_L (0xce), Hyper_L (0xcf)
mod5 ISO_Level3_Shift (0x5c), Mode_switch (0xcb)
我跑过去xev
看到以下内容:
左选项:
KeyPress event, serial 38, synthetic NO, window 0x2000001,
root 0x3e, subw 0x0, time 19839468, (104,80), root:(106,131),
state 0x0, keycode 203 (keysym 0xff7e, Mode_switch), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
PropertyNotify event, serial 38, synthetic NO, window 0x2000001,
atom 0x11c (XKLAVIER_STATE), time 19839468, state PropertyNewValue
PropertyNotify event, serial 38, synthetic NO, window 0x2000001,
atom 0x11c (XKLAVIER_STATE), time 19839468, state PropertyNewValue
左命令:
KeyPress event, serial 38, synthetic NO, window 0x2000001,
root 0x3e, subw 0x0, time 19937256, (103,75), root:(105,126),
state 0x0, keycode 64 (keysym 0xffe9, Alt_L), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
右选项:
KeyPress event, serial 38, synthetic NO, window 0x2000001,
root 0x3e, subw 0x0, time 19987161, (132,152), root:(134,203),
state 0x0, keycode 9 (keysym 0xff1b, Escape), same_screen YES,
XLookupString gives 1 bytes: (1b) ""
XmbLookupString gives 1 bytes: (1b) ""
XFilterEvent returns: False
右键命令:
KeyPress event, serial 38, synthetic NO, window 0x2000001,
root 0x3e, subw 0x0, time 20026188, (93,166), root:(95,217),
state 0x0, keycode 133 (keysym 0xffeb, Super_L), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
因此,我尝试了以下操作xmodmap
:
! Map the right Macintosh Command key to Meta:
remove mod4 = Super_L
add mod1 = Super_L
! Map the left Macintosh Option key to Meta:
remove mod5 = Mode_switch
add mod1 = Mode_switch
! Map the right Macintosh Option key to Meta:
remove mod5 = ISO_Level3_Shift
add mod1 = ISO_Level3_Shift
通过以下方式导致此状态xmodmap -pm
:
xmodmap: up to 7 keys per modifier, (keycodes in parentheses):
shift Shift_L (0x32), Shift_R (0x3e)
lock Caps_Lock (0x42)
control Control_L (0x25), Control_R (0x69)
mod1 Alt_L (0x40), ISO_Level3_Shift (0x5c), Alt_R (0x6c), Super_L (0x85), Mode_switch (0xcb), Meta_L (0xcd), Super_L (0xce)
mod2 Num_Lock (0x4d)
mod3
mod4 Super_R (0x86), Hyper_L (0xcf)
mod5
但这表现得很糟糕:
- 左选项-x => 不正确:
≈
- 左命令-x => 错误:
M-b
- 右选项-x => 不正确:
M-≈
- 右命令-x => 错误:
M-b
请注意,Dvorak 上的“x”键对应于 Qwerty 上的“b”键。
使用xev
我现在得到:
左选项:

因此,我不清楚如何解决此问题并获得两个选项和两个命令键的所需行为,就像meta
在带有 Dvorak 键盘的 Emacs 中一样。
