| 1695 /* X bogusly doesn't define the interpretations of any bits besides | |
| 1696 ModControl, ModShift, and ModLock; so the Interclient Communication | |
| 1697 Conventions Manual says that we have to bend over backwards to figure | |
| 1698 out what the other modifier bits mean. According to ICCCM: | |
| 1699 | |
| 1700 - Any keycode which is assigned ModControl is a "control" key. | |
| 1701 | |
| 1702 - Any modifier bit which is assigned to a keycode which generates Meta_L | |
| 1703 or Meta_R is the modifier bit meaning "meta". Likewise for Super, Hyper, | |
| 1704 etc. | |
| 1705 | |
| 1706 - Any keypress event which contains ModControl in its state should be | |
| 1707 interpreted as a "control" character. | |
| 1708 | |
| 1709 - Any keypress event which contains a modifier bit in its state which is | |
| 1710 generated by a keycode whose corresponding keysym is Meta_L or Meta_R | |
| 1711 should be interpreted as a "meta" character. Likewise for Super, Hyper, | |
| 1712 etc. | |
| 1713 | |
| 1714 - It is illegal for a keysym to be associated with more than one modifier | |
| 1715 bit. | |
| 1716 | |
| 1717 This means that the only thing that emacs can reasonably interpret as a | |
| 1718 "meta" key is a key whose keysym is Meta_L or Meta_R, and which generates | |
| 1719 one of the modifier bits Mod1-Mod5. | |
| 1720 | |
| 1721 Unfortunately, many keyboards don't have Meta keys in their default | |
| 1722 configuration. So, if there are no Meta keys, but there are "Alt" keys, | |
| 1723 emacs will interpret Alt as Meta. If there are both Meta and Alt keys, | |
| 1724 then the Meta keys mean "Meta", and the Alt keys mean "Alt" (it used to | |
| 1725 mean "Symbol," but that just confused the hell out of way too many people). | |
| 1726 | |
| 1727 This works with the default configurations of the 19 keyboard-types I've | |
| 1728 checked. | |
| 1729 | |
| 1730 Emacs detects keyboard configurations which violate the above rules, and | |
| 1731 prints an error message on the standard-error-output. (Perhaps it should | |
| 1732 use a pop-up-window instead.) | |
