Hello

I would like to know how to change the default keyboard mapping for Linux console and X. Let me give you specific example:
I have a non US-keyboard where the "{" symbol is achieved with combination Alt-Gr + "7". I would like to change the keyboard mapping in a way that, besides this combination, the same symbol "{" is generated with the combination Alt_L + Shift + "7".
I need this feature because recently I have purchased a Mac computer that, as you know, doesn't have the Alt-Gr key. To work I frequently connect to a Linux workstation through VNC and typing Alt_L + Shift + "7" does not produce the "{" that I need.

Thanks very much in advance

Im not sure if its possible to use key sequences, but kbd is what is used to select keymaps for the console. As for X, its entirely independent from the base OS, but it provides xmodmap, which can be used to modify keyboard and mouse bindings. In X, more complex input methods do exist for internationalization, so im sure they support key sequence bindings if xmodmap doesn't.

Is kbd available from the user shell ? I don't find such command.

kbd is a project/package, in it, loadkeys allows you use load keyboard mappings, tho, im also sure there is also a command to bind single keys, if not a option.

according to gentoo, its homepage is on: http://freshmeat.net/projects/kbd/ (ok, so it doesn't have a homepage apparently).

list of commands it comes with:

/usr/bin/dumpkeys
/usr/bin/openvt
/usr/bin/showkey
/usr/bin/setfont
/usr/bin/showconsolefont
/usr/bin/setleds
/usr/bin/setmetamode
/usr/bin/kbd_mode
/usr/bin/chvt
/usr/bin/deallocvt
/usr/bin/psfxtable
/usr/bin/kbdrate
/usr/bin/fgconsole
/usr/bin/getkeycodes
/usr/bin/setkeycodes
/usr/bin/resizecons
/usr/bin/mapscrn
/usr/bin/loadunimap
/usr/bin/unicode_start
/usr/bin/unicode_stop
/usr/bin/psfaddtable
/usr/bin/psfgettable
/usr/bin/psfstriptable
/bin/loadkeys
/bin/setfont

that might help.
