ubuntu下的key remap功能

今天去新公司报到，结果要直接在PC上安装ubuntu系统来开发，而不是用虚拟机，晕死，一下子弄的我简直像个白痴，每次想编辑一个文件，或者想进出目录，简直就是白痴，最后还是受不了，在ubuntu上安装了emacs，还好最后我发现有个很好的key remap工具提供给X11的键映射，爽 ～～～～

用emacs就肯定要对换一下Caps_Lock和Control_L这两个键，除非他喜欢自残，这个我没法阻止 ～～～

只需要在使用时输入命令就搞定： xmodmap swap_key

而且支持切换回来，太好了～～～

file: swap_key

!
! Swap Caps_Lock and Control_L
!
remove Lock = Caps_Lock
remove Control = Control_L
keysym Control_L = Caps_Lock
keysym Caps_Lock = Control_L
add Lock = Caps_Lock
add Control = Control_L

---------------------------------------------------------------------------------------------

还有补充一点关于在Microsoft Windows下改变映射键的工具，以前一直用那个RemapKey工具，经常被杀毒软件杀掉，明天尝试一下KeyTweak，看那赛门铁克还能不能克这个 ～～～ 不爽

NAME

xmodmap  - utility for modifying keymaps and pointer button mappings in
X


SYNOPSIS

xmodmap [-options ...] [filename]


DESCRIPTION

The xmodmap program is used to edit and display the  keyboard  modifier
map  and  keymap  table that are used by client applications to convert
event keycodes into keysyms.  It is usually run from the user’s session
startup  script to configure the keyboard according to personal tastes.


OPTIONS

The following options may be used with xmodmap:

-display display
This option specifies the host and display to use.

-help   This option indicates that a brief description of  the  command
line arguments should be printed on the standard error channel.
This will be done whenever an unhandled argument  is  given  to
xmodmap.

-grammar
This  option  indicates  that  a  help  message  describing the
expression grammar used in files and with -e expressions should
be printed on the standard error.

-verbose
This   option  indicates  that  xmodmap  should  print  logging
information as it parses its input.

-quiet  This option  turns  off  the  verbose  logging.   This  is  the
default.

-n      This  option  indicates  that  xmodmap  should  not  change the
mappings, but should display what it  would  do,  like  make(1)
does when given this option.

-e expression
This option specifies an expression to be executed.  Any number
of expressions may be specified from the command line.

-pm     This option indicates that the current modifier map  should  be
printed  on  the standard output.   This is the default mode of
operation if no other mode options are specified.

-pk     This option indicates that the current keymap table  should  be
printed on the standard output.

-pke    This  option  indicates that the current keymap table should be
printed on the standard output in the form of expressions  that
can be fed back to xmodmap.

-pp     This  option  indicates  that the current pointer map should be
printed on the standard output.

-       A lone dash means that the standard input should be used as the
input file.

The  filename  specifies  a  file  containing xmodmap expressions to be
executed.  This file is usually kept in the user’s home directory  with
a name like .xmodmaprc.


EXPRESSION GRAMMAR

The  xmodmap  program  reads  a list of expressions and parses them all
before attempting to execute any of them.  This makes  it  possible  to
refer  to  keysyms  that  are  being redefined in a natural way without
having to worry as much about name conflicts.

keycode NUMBER = KEYSYMNAME ...
The list of keysyms is assigned to the indicated keycode (which
may be specified in decimal, hex or octal and can be determined
by running the xev  program).   Up  to  eight  keysyms  may  be
attached  to  a  key, however the last four are not used in any
major X server implementation.  The first keysym is  used  when
no  modifier  key  is pressed in conjunction with this key, the
second with Shift, the third when the Mode_switch key  is  used
with  this  key  and  the  fourth when both the Mode_switch and
Shift keys are used.

keycode any = KEYSYMNAME ...
If no existing key has the specified list of  keysyms  assigned
to  it, a spare key on the keyboard is selected and the keysyms
are assigned to it.  The list of keysyms may  be  specified  in
decimal, hex or octal.

keysym KEYSYMNAME = KEYSYMNAME ...
The  KEYSYMNAME  on  the  left  hand  side  is  translated into
matching keycodes used to  perform  the  corresponding  set  of
keycode  expressions.  The list of keysym names may be found in
the header file  (without the XK_  prefix)  or
the  keysym  database   /usr/share/X11/XKeysymDB.  Note that if
the same keysym is bound to multiple keys,  the  expression  is
executed for each matching keycode.

clear MODIFIERNAME
This  removes  all  entries  in  the modifier map for the given
modifier, where valid name are:  Shift,  Lock,  Control,  Mod1,
Mod2,  Mod3,  Mod4,  and Mod5 (case does not matter in modifier
names, although it does  matter  for  all  other  names).   For
example,  ‘‘clear  Lock’’  will  remove  all any keys that were
bound to the shift lock modifier.

add MODIFIERNAME = KEYSYMNAME ...
This  adds  all  keys  containing  the  given  keysyms  to  the
indicated  modifier  map.  The keysym names are evaluated after
all input expressions  are  read  to  make  it  easy  to  write
expressions to swap keys (see the EXAMPLES section).

remove MODIFIERNAME = KEYSYMNAME ...
This  removes  all  keys  containing the given keysyms from the
indicated modifier map.   Unlike  add,  the  keysym  names  are
evaluated  as  the  line is read in.  This allows you to remove
keys from a modifier without having to worry about  whether  or
not they have been reassigned.

pointer = default
This  sets the pointer map back to its default settings (button
1 generates a code of 1, button 2 generates a 2, etc.).

pointer = NUMBER ...
This sets the pointer  map  to  contain  the  indicated  button
codes.   The list always starts with the first physical button.

Lines that begin with an exclamation point (!) are taken as comments.

If you want to change the binding of a  modifier  key,  you  must  also
remove it from the appropriate modifier map.


EXAMPLES

Many  pointers are designed such that the first button is pressed using
the index finger  of  the  right  hand.   People  who  are  left-handed
frequently find that it is more comfortable to reverse the button codes
that get generated so that the primary  button  is  pressed  using  the
index  finger  of  the  left  hand.   This  could be done on a 3 button
pointer as follows:

%  xmodmap -e "pointer = 3 2 1"

Many applications support the notion of Meta keys (similar  to  Control
keys  except that Meta is held down instead of Control).  However, some
servers do not have a Meta keysym in the default keymap table,  so  one
needs  to  be added by hand.  The following command will attach Meta to
the Multi-language key (sometimes labeled Compose Character).  It  also
takes  advantage  of  the  fact  that applications that need a Meta key
simply need to get the keycode and don’t require the keysym  to  be  in
the  first  column  of  the keymap table.  This means that applications
that are looking for a Multi_key (including the default  modifier  map)
won’t notice any change.

%  xmodmap -e "keysym Multi_key = Multi_key Meta_L"

Similarly,  some  keyboards  have  an Alt key but no Meta key.  In that
case the following may be useful:

%  xmodmap -e "keysym Alt_L = Meta_L Alt_L"

One of the more simple, yet convenient, uses of xmodmap is to  set  the
keyboard’s   "rubout"  key  to  generate  an  alternate  keysym.   This
frequently  involves  exchanging  Backspace  with  Delete  to  be  more
comfortable  to  the user.  If the ttyModes resource in xterm is set as
well, all terminal emulator windows will use the same key  for  erasing
characters:

%  xmodmap -e "keysym BackSpace = Delete"
%  echo "XTerm*ttyModes:  erase ^?" | xrdb -merge

Some keyboards do not automatically generate less than and greater than
characters when the comma and period keys are  shifted.   This  can  be
remedied  with  xmodmap  by  resetting  the  bindings for the comma and
period with the following scripts:

!
! make shift-, be < and shift-. be >
!
keysym comma = comma less
keysym period = period greater

One of  the  more  irritating  differences  between  keyboards  is  the
location  of  the Control and Shift Lock keys.  A common use of xmodmap
is to swap these two keys as follows:

!
! Swap Caps_Lock and Control_L
!
remove Lock = Caps_Lock
remove Control = Control_L
keysym Control_L = Caps_Lock
keysym Caps_Lock = Control_L
add Lock = Caps_Lock
add Control = Control_L

This example can be run again to swap the keys back to  their  previous
assignments.

The keycode command is useful for assigning the same keysym to multiple
keycodes.  Although unportable, it also  makes  it  possible  to  write
scripts  that  can  reset the keyboard to a known state.  The following
script sets the backspace key to  generate  Delete  (as  shown  above),
flushes  all  existing  caps lock bindings, makes the CapsLock key be a
control key, make F5 generate Escape, and makes Break/Reset be a  shift
lock.

!
! On the HP, the following keycodes have key caps as listed:
!
!     101  Backspace
!      55  Caps
!      14  Ctrl
!      15  Break/Reset
!      86  Stop
!      89  F5
!
keycode 101 = Delete
keycode 55 = Control_R
clear Lock
add Control = Control_R
keycode 89 = Escape
keycode 15 = Caps_Lock
add Lock = Caps_Lock


ENVIRONMENT

DISPLAY to get default host and display number.

BUGS

Every  time  a  keycode expression is evaluated, the server generates a
MappingNotify event on every client.  This can  cause  some  thrashing.
All  of  the  changes  should  be  batched  together  and done at once.
Clients that receive keyboard input  and  ignore  MappingNotify  events
will not notice any changes made to keyboard mappings.

Xmodmap  should  generate  "add" and "remove" expressions automatically
whenever a keycode that is already bound to a modifier is changed.

There should be a way to have the remove expression accept keycodes  as
well  as keysyms for those times when you really mess up your mappings.
