I have in mind a remapping of function keys for a
retargetable user interface. Namely, I will remap the function
keys for the application based on what function keys the hardware
provides. X in fact provides a lot of flexibility here.
However if I try to use XRebindKeysym to rebind function
keys with modifiers (as the documentation seems to indicate
is possible) I can never look up these values with XLookupString.
For example, if I rebind Left function key 1, or L1, (known to X
as keysym XK_L1) with say modifer XK_Meta_L, specified in the
modifier list of KeySym-s, I never see the binding for that
key with the modifier.
Instead, I see the binding for the unmodified L1. It's almost as
if the modifier is being ignored...
I went runging around in XKeyBind.c and couldn't really find the
problem. I am pretty sure I have the arguments for modifiers
coded correctly (the list is a list of keysyms which are to be
used as modifiers), but I do not understand the implementation
well enough to be able to fix the problem.
The comments in the code seem to suggest that allowing
XtranslateKey to return a function key modified by Ctrl,
Shift, etc, would be dictating policy. I hope no-one would
argue that, since the hardware keyboard dictates the key
impulses that get generated, what will be a modifier, and what
not.dshr@SUN.COM (David Rosenthal) (04/13/88)

I think you are being too optimistic here. It is far from clear that,
in a multi-lingual environment, it is even meaningful to
bind strings to keys globally.
It is possible to argue that a group of related clients, perhaps
all those using an ISO Latin 1 encoding, would want to use the
same key-to-string bindings.

Make sure that this is all happening within the same client. The XRebindKeysym call is used within a single process and does not send any information to the server. Global, arbitrary binding of strings to keys is still being designed. If this isn't problem then a small example of code along with a description of which release of X, the operating system, and the display being used would be useful. Jim Fulton MIT X Consortium
