Bug#610263: xkb-data: Mapping Prior and Next to Mod3+U and Mod3+I clobbers Shift+U and Shift+I
Package: xkb-data
Version: 1.3-2
Severity: normal
I created a custom layout called "cjns" in /usr/etc/X11/xkb/symbols
where among other things, the ‘navigation keypad’ is remapped to
Mod3+[UIOP] (PgUp, PgDn, Home, End) and Mod3+[HJKL] (Arrow keys).
The navigation keys all work fine where I need them, for instance in the
seamonkey/mozilla browser, but I noticed that the Shift+U and Shift+I,
the keys that have a 3rd level mapping to Prior and Next, no longer
produce an upper case U or an upper case I.
What makes me suspect that the problem is with the xkb package rather
than XTerm is that I get similar results with other traditional
X applications, such as Xman (Xman has a text-entry field under the
‘Search’ option).
To recreate the problem:
// duplicate the standard ‘us’ layout under another name:
partial alphanumeric_keys
xkb_symbols "cjns" {
name[Group1]= "USA - cjns";
....
// add 3rd level definitions of ‘Prior’ and ’Next’, e.g.:
key <AD07> { [ u, U, Prior, NoSymbol ] };
key <AD08> { [ i, I, Next, NoSymbol ] };
....
// map Mod3 to the windows keys:
include "level3(win_switch)"
};
After enabling the custom keyboard layout via ‘setxkbmap cjns’, the
shifted forms of the ‘U’ and ’I’ keys no longer work when typed in an
XTerm, or other X applications.
Workaround:
Mapping KP_Prior and KP_Next to the same keys do not cause the problem:
key <AD07> { [ u, U, KP_Prior, NoSymbol ] };
key <AD08> { [ i, I, KP_Next, NoSymbol ] };
Additional remarks:
With the initial mapping (Prior/Next), Shift+U and Shift+I appear to be
mapped to Shift+Prior and Shift+Next respectively.
In an XTerm, this can be verified by typing Shift+U and Shift+I, which
results in scrolling the XTerm's input/output history.
