Well, after doing more tests, this is actually more complex.
The problem is that keysyms that correspond to F1 and Shift-F8
*when xpdf is started* do not work.
If I remap the keyboard with xkbcomp while xpdf is running, then the
new mapping is taken into account, except that the keysyms mentioned
above still do not work. For instance, if I swap the F1 & F2 settings
and the F7 & F8 settings while xpdf is running, then this is F2 and
Shift-F7 that do not work.
I reassign this bug to libxm4 since the bug probably occurs at the
Motif level. I notice that libmotif-common provides bindings files
(/usr/share/X11/bindings directory), where one can see settings for
F1 and Shift-F8, but also F10 and Shift-F10. However:
* I don't have any problem with F10 and Shift-F10.
* No such bindings files are read when running xpdf, as shown
by strace -f.
I suspect that Motif may have default bindings for F1 and Shift-F8
(the string "_MOTIF_DEFAULT_BINDINGS" appears in strace output).
It is wrong to override the user's keyboard mapping.
