1693 /* X bogusly doesn't define the interpretations of any bits besides | |
1694 ModControl, ModShift, and ModLock; so the Interclient Communication | |
1695 Conventions Manual says that we have to bend over backwards to figure | |
1696 out what the other modifier bits mean. According to ICCCM: | |
1697 | |
1698 - Any keycode which is assigned ModControl is a "control" key. | |
1699 | |
1700 - Any modifier bit which is assigned to a keycode which generates Meta_L | |
1701 or Meta_R is the modifier bit meaning "meta". Likewise for Super, Hyper, | |
1702 etc. | |
1703 | |
1704 - Any keypress event which contains ModControl in its state should be | |
1705 interpreted as a "control" character. | |
1706 | |
1707 - Any keypress event which contains a modifier bit in its state which is | |
1708 generated by a keycode whose corresponding keysym is Meta_L or Meta_R | |
1709 should be interpreted as a "meta" character. Likewise for Super, Hyper, | |
1710 etc. | |
1711 | |
1712 - It is illegal for a keysym to be associated with more than one modifier | |
1713 bit. | |
1714 | |
1715 This means that the only thing that emacs can reasonably interpret as a | |
1716 "meta" key is a key whose keysym is Meta_L or Meta_R, and which generates | |
1717 one of the modifier bits Mod1-Mod5. | |
1718 | |
1719 Unfortunately, many keyboards don't have Meta keys in their default | |
1720 configuration. So, if there are no Meta keys, but there are "Alt" keys, | |
1721 emacs will interpret Alt as Meta. If there are both Meta and Alt keys, | |
1722 then the Meta keys mean "Meta", and the Alt keys mean "Alt" (it used to | |
1723 mean "Symbol," but that just confused the hell out of way too many people). | |
1724 | |
1725 This works with the default configurations of the 19 keyboard-types I've | |
1726 checked. | |
1727 | |
1728 Emacs detects keyboard configurations which violate the above rules, and | |
1729 prints an error message on the standard-error-output. (Perhaps it should | |
1730 use a pop-up-window instead.) | |
