DESCRIPTION
The 1/Motif manual pages describe translations in terms of virtual
bindings, based on those described in the OSF/Motif Style Guide. Mouse
events are described in terms of virtual buttons, and key events are
described in terms of virtual keys. The term virtual implies that the
events as described do not necessarily correspond to a fixed set of X
Window System events. Instead, virtual buttons and keys are linked to
actual events by means of virtual bindings.
Virtual Modifiers
Both virtual buttons and virtual keys may contain virtual modifiers.
Each virtual modifier corresponds to one or more actual modifiers. The
following table lists the bindings of virtual modifiers to actual modi‐
fiers in 1/Motif:
────────────────────────────────────
Virtual Modifier Bindings
Virtual Modifier Actual Modifiers
────────────────────────────────────
MAlt Mod1
MCopy Ctrl
MCtrl Ctrl
MLink Ctrl Shift
MMove Shift
MShift Shift
────────────────────────────────────
Mod1 refers to the first modifier key. 1/Motif requires that it corre‐
spond to either Alt or Meta.
The virtual modifier MAny indicates that any modifier can be used. If
MAny is not specified and the user presses an actual modifier that is
not explicitly included in a translation, that modifier may prevent the
translation from being matched.
Virtual Buttons
Each virtual button corresponds to one or more actual button event
descriptions. Each button event description contains a button name and
possibly modifiers. These button event descriptions, appropriately
ordered and possibly further modified, are used in translation tables.
The following table lists the bindings of virtual buttons to actual
button event descriptions in 1/Motif:

Virtual Keys
Each virtual key corresponds to one or more actual key event descrip‐
tions. Each key event description contains a keysym name and possibly
modifiers. These key event descriptions, appropriately ordered and
possibly further modified, are used in translation tables. The follow‐
ing table lists the bindings of virtual keys to actual key event
descriptions in 1/Motif:

Bindings for osf Keysyms
Keysym strings that begin with “osf” are not part of the X server's
keyboard mapping. Instead, these keysyms are produced on the client
side at run time. They are interpreted by the routine XmTranslateKey,
and are used by the translation manager when the server delivers an
actual key event. For each application, a mapping is maintained between
“osf” keysyms and keysyms that correspond to actual keys. This mapping
is based on information obtained at application startup from one of the
following sources, listed in order of precedence: A defaultVirtualBind‐
ings application resource in the resource database. A property on the
root window, which can be set by mwm on startup, or by the xmbind
client, or on prior startup of a Motif application. The file in the
user's home directory. A set of bindings based on the vendor string
and optionally the vendor release of the X server. Motif searches for
these bindings in the following steps: If the file xmbind.alias exists
in the user's home directory, Motif searches this file for a pathname
associated with the vendor string or with the vendor string and vendor
release. If it finds such a pathname and if that file exists, Motif
loads the bindings contained in that file. If it has found no bind‐
ings, Motif next looks for the file xmbind.alias in the directory spec‐
ified by the environment variable XMBINDDIR, if XMBINDDIR is set, or in
the directory /usr/lib/Xm/bindings if XMBINDDIR is not set. If this
file exists Motif searches it for a pathname associated with the vendor
string or with the vendor string and vendor release. If it finds such
a pathname and if that file exists, Motif loads the bindings contained
in that file. If it still has found no bindings, Motif loads a set of
hard-coded fallback bindings.
The xmbind.alias file contains zero or more lines of the form:
"vendor_string[vendor_release]" bindings_file
where vendor_string is the X server vendor name as returned by the X
client xdpyinfo or the Xlib function XServerVendor, and must appear in
double quotes. If vendor_release is included, it is the X server vendor
release number as returned by the X client xdpyinfo or the Xlib func‐
tion XVendorRelease, and must also be contained within the double
quotes separated by one space from vendor_string. vendor_release is
provided to allow support of changes in keyboard hardware from a ven‐
dor, assuming that the vendor increments the release number to flag
such changes. Alternatively, the vendor may simply use a unique vendor
string for each different keyboard.
bindings_file is the pathname of the file containing the bindings them‐
selves. It can be a relative or absolute pathname. If it is a relative
pathname, it is relative to the location of the xmbind.alias file.
Comment lines in the xmbind.alias file begin with !.
The bindings found in either the file or the vendor mapping are placed
in a property on the root window. This property is used to determine
the bindings for subsequent Motif applications.
On startup mwm attempts to load the file in the user's home directory.
If this is unsuccessful, it loads the vendor bindings as described
above. It places the bindings it loads in a property on the root window
for use by subsequent Motif applications.
xmbind loads bindings from a file if that file is specified on the com‐
mand line. If no file is specified on the command line, it attempts to
load the file in the user's home directory. If this fails, it loads the
vendor bindings as described above. It places the bindings it loads in
a property on the root window for use by subsequent Motif applications.
The format of the specification for mapping “osf” keysyms to actual
keysyms is similar to that of a specification for an event translation.
The syntax is specified here in EBNF notation using the following con‐
ventions: Means either nothing or a Means zero or more occurrences of a
Terminals are enclosed in double quotation marks.
The syntax of an “osf” keysym binding specification is as follows:
binding_spec = {line "\n"} [line] line = virtual_keysym ":"
key_event key_event = {modifier_name} "<Key>" actual_keysym vir‐
tual_keysym = keysym actual_keysym = keysym keysym = A valid
X11 keysym name that is
mapped by XStringToKeysym
As with event translations, more specific event descriptions must pre‐
cede less specific descriptions. For example, an event description for
a key with a modifier must precede a description for the same key with‐
out the same modifier.
Following is an example of a specification for the defaultVirtualBind‐
ings resource in a resource file:
*defaultVirtualBindings: \
osfBackSpace : <Key>BackSpace\n\
osfInsert : <Key>InsertChar\n\ ...
osfDelete : <Key>DeleteChar
The format of a file or of a file containing vendor bindings is the
same, except that the binding specification for each keysym is placed
on a separate line. The example specification above appears as follows
in a or vendor bindings file:
osfBackSpace : <Key>BackSpace osfInsert : <Key>InsertChar
... osfDelete : <Key>DeleteChar
