(e.g., windows hotkeys in virtualbox similarly, if we put mod key as alt, it causes trouble using emacs). any solution for this issue? thanks in advanceTue, 24 Sep 2013 02:01:20 +0000https://faq.i3wm.org/question/2569/set-mod-key-only-as-left-mod-key/https://faq.i3wm.org/question/2569/set-mod-key-only-as-left-mod-key/?answer=2580#post-id-2580You have to use xmodmap to remap the modifiers. If run without arguments it will show the current modifier mapping: $ xmodmap 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) In my case you might note that `mod3` is unused, and `Super_R` and `Super_L` are both assigned to mod4. You can now remove the assignment of `Super_R` to `mod4` by $ xmodmap -e 'remove Mod4 = Super_R' and then redefine $ xmodmap -e 'add Mod3 = Super_R' This will give you $ xmodmap xmodmap: up to 3 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 Super_R (0x86) mod4 Super_L (0x85), Super_L (0xce), Hyper_L (0xcf) mod5 ISO_Level3_Shift (0x5c), Mode_switch (0xcb) Then you should be able to use `set $mod mod3` in your i3 config to only mean the right super key while preserving the regular function of the left super key for other applications. Of course once you've got it right you might want to add those commands to your ~/.xsession (or create one as outlined in the manpage of i3).

Untested, but `xmodmap -e "remove mod4 = Super_R"` could work.Wed, 25 Sep 2013 16:38:04 +0000https://faq.i3wm.org/question/2569/set-mod-key-only-as-left-mod-key/?answer=2579#post-id-2579https://faq.i3wm.org/question/2569/set-mod-key-only-as-left-mod-key/?comment=2591#comment-2591I got it, you have to assign super_R to some where else before making it working. just like $ xmodmap -e "add mod3 = Super_R"Thu, 26 Sep 2013 01:47:31 +0000https://faq.i3wm.org/question/2569/set-mod-key-only-as-left-mod-key/?comment=2591#comment-2591https://faq.i3wm.org/question/2569/set-mod-key-only-as-left-mod-key/?comment=2590#comment-2590i tried that, but it does not work (both super key are still working as $mod key in i3), even if $xmodmap gives mod4 Super_L (0x85), Super_L (0xce), Hyper_L (0xcf) Thu, 26 Sep 2013 01:39:48 +0000https://faq.i3wm.org/question/2569/set-mod-key-only-as-left-mod-key/?comment=2590#comment-2590
