BBBBiiiinnnnddddiiiinnnnggggssss ffffoooorrrr oooossssffff KKKKeeeeyyyyssssyyyymmmmssss Keysym strings that begin with <<<<oooossssffff>>>> 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 XXXXmmmmTTTTrrrraaaannnnssssllllaaaatttteeeeKKKKeeeeyyyy, and are used by the translation manager when the server delivers an actual key event. For each application, a mapping is maintained between <<<<oooossssffff>>>> 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: +o The XXXXmmmmNNNNddddeeeeffffaaaauuuullllttttVVVViiiirrrrttttuuuuaaaallllBBBBiiiinnnnddddiiiinnnnggggssss resource from Display. +o A property on the root window, which can be set by mmmmwwwwmmmm on startup, or by the xxxxmmmmbbbbiiiinnnndddd client, or on prior startup of a Motif application. +o The file ....mmmmoooottttiiiiffffbbbbiiiinnnndddd in the user's home directory. +o 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: 0. If the file xxxxmmmmbbbbiiiinnnndddd....aaaalllliiiiaaaassss 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. 1. If it has found no bindings, Motif next looks for the file xxxxmmmmbbbbiiiinnnndddd....aaaalllliiiiaaaassss in the directory specified by the environment variable XXXXMMMMBBBBIIIINNNNDDDDDDDDIIIIRRRR, if XXXXMMMMBBBBIIIINNNNDDDDDDDDIIIIRRRR is set, or in the directory ////uuuussssrrrr////lllliiiibbbb////XXXXmmmm////bbbbiiiinnnnddddiiiinnnnggggssss if XXXXMMMMBBBBIIIINNNNDDDDDDDDIIIIRRRR 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. Page 1 (printed 10/24/98) VVVViiiirrrrttttuuuuaaaallllBBBBiiiinnnnddddiiiinnnnggggssss((((lllliiiibbbbrrrraaaarrrryyyy ccccaaaallllUUUUllllNNNN))))IIIIXXXX SSSSyyyysssstttteeeemmmmVVVViiiiVVVVrrrrttttuuuuaaaallllBBBBiiiinnnnddddiiiinnnnggggssss((((lllliiiibbbbrrrraaaarrrryyyy ccccaaaallllllll)))) 2. If it still has found no bindings, Motif loads a set of hard-coded fallback bindings. The xxxxmmmmbbbbiiiinnnndddd....aaaalllliiiiaaaassss file contains zero or more lines of the following form: "_v_e_n_d_o_r__s_t_r_i_n_g[ _v_e_n_d_o_r__r_e_l_e_a_s_e]" _b_i_n_d_i_n_g_s__f_i_l_e where _v_e_n_d_o_r__s_t_r_i_n_g is the X server vendor name as returned by the X client xxxxddddppppyyyyiiiinnnnffffoooo or the Xlib function XXXXSSSSeeeerrrrvvvveeeerrrrVVVVeeeennnnddddoooorrrr, and must appear in double quotes. If _v_e_n_d_o_r__r_e_l_e_a_s_e is included, it is the X server vendor release number as returned by the X client xxxxddddppppyyyyiiiinnnnffffoooo or the Xlib function XXXXVVVVeeeennnnddddoooorrrrRRRReeeelllleeeeaaaasssseeee, and must also be contained within the double quotes separated by one space from _v_e_n_d_o_r__s_t_r_i_n_g. The _v_e_n_d_o_r__r_e_l_e_a_s_e argument is provided to allow support of changes in keyboard hardware from a vendor, 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. The _b_i_n_d_i_n_g_s__f_i_l_e argument is the pathname of the file containing the bindings themselves. It can be a relative or absolute pathname. If it it is a relative pathname, it is relative to the location of the xxxxmmmmbbbbiiiinnnndddd....aaaalllliiiiaaaassss file. Comment lines in the xxxxmmmmbbbbiiiinnnndddd....aaaalllliiiiaaaassss file begin with ! (exclamation point). The bindings found in either the ....mmmmoooottttiiiiffffbbbbiiiinnnndddd 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 mmmmwwwwmmmm attempts to load the file ....mmmmoooottttiiiiffffbbbbiiiinnnndddd in the user's home directory. If this is unsuccessful, it loads the vendor bindings as described previously. It places the bindings it loads in a property on the root window for use by subsequent Motif applications. The xxxxmmmmbbbbiiiinnnndddd function loads bindings from a file if that file is specified on the command line. If no file is specified on the command line, it attempts to load the file ....mmmmoooottttiiiiffffbbbbiiiinnnndddd in the user's home directory. If this fails, it loads the vendor bindings as described previously. 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 <<<<oooossssffff>>>> keysyms to actual keysyms is similar to that of a specification for an event translation. (See below) The syntax is specified (and below) here in EBNF notation using the following Page 2 (printed 10/24/98) VVVViiiirrrrttttuuuuaaaallllBBBBiiiinnnnddddiiiinnnnggggssss((((lllliiiibbbbrrrraaaarrrryyyy ccccaaaallllUUUUllllNNNN))))IIIIXXXX SSSSyyyysssstttteeeemmmmVVVViiiiVVVVrrrrttttuuuuaaaallllBBBBiiiinnnnddddiiiinnnnggggssss((((lllliiiibbbbrrrraaaarrrryyyy ccccaaaallllllll)))) conventions: [_a] Means either nothing or _a{_a} Means zero or more occurrences of _a(_a|_b) Means either _a or _b. Terminals are enclosed in double quotation marks. The syntax of an <<<<oooossssffff>>>> keysym binding specification is as follows: binding_spec = {line "\n"} [line] line = virtual_keysym ":" list_of_key_event list_of_key_event= key_event { "," key_event} key_event = {modifier_name} "<Key>" actual_keysym virtual_keysym = keysym actual_keysym = keysym keysym = A valid X11 keysym name that is mapped by XXXXSSSSttttrrrriiiinnnnggggTTTTooooKKKKeeeeyyyyssssyyyymmmm As with event translations, more specific event descriptions must precede less specific descriptions. For example, an event description for a key with a modifier must precede a description for the same key without the same modifier. Following is an example of a specification for the ddddeeeeffffaaaauuuullllttttVVVViiiirrrrttttuuuuaaaallllBBBBiiiinnnnddddiiiinnnnggggssss resource in a resource file: *defaultVirtualBindings: \ osfBackSpace: <Key>BackSpace \n\ osfInsert: <Key>InsertChar \n\ osfDelete: <Key>DeleteChar \n\ ... osfLeft: <Key>left, Ctrl<Key>H The format of a ....mmmmoooottttiiiiffffbbbbiiiinnnndddd 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 previous example specification appears as follows in a ....mmmmoooottttiiiiffffbbbbiiiinnnndddd or vendor bindings file: osfBackSpace: <Key>BackSpace osfInsert: <Key>InsertChar osfDelete: <Key>DeleteChar ... osfLeft: <Key>left, Ctrl<Key>H The following table lists the fixed fallback default bindings for <<<<oooossssffff>>>> keysyms.

This change allows the numeric keypad to be used to generate numbers using the standard X mechanisms. Since the default behavior is now to honor the xmodmap keymap bindings, translations and virtual key bindings that use <Shift> may behave differently. A common symptom is that unshifted keypad and function keys (with or without other modifiers) produce the expected Page 4 (printed 10/24/98) VVVViiiirrrrttttuuuuaaaallllBBBBiiiinnnnddddiiiinnnnggggssss((((lllliiiibbbbrrrraaaarrrryyyy ccccaaaallllUUUUllllNNNN))))IIIIXXXX SSSSyyyysssstttteeeemmmmVVVViiiiVVVVrrrrttttuuuuaaaallllBBBBiiiinnnnddddiiiinnnnggggssss((((lllliiiibbbbrrrraaaarrrryyyy ccccaaaallllllll)))) results, but shifted ones do not. To obtain the old behavior you can remove the shifted interpretation from problematic keys using the xxxxmmmmooooddddmmmmaaaapppp utility. Each entry in a xxxxmmmmooooddddmmmmaaaapppp keymap table contains up to four keysym bindings. The second and fourth keysyms are for shifted keys. If an expression contains only two keysyms, simply remove the second keysym. If an entry contains three or more keysyms, replace the second keysym with NNNNooooSSSSyyyymmmmbbbboooollll and remove the fourth keysym. AAAAccccttttiiiioooonnnn TTTTrrrraaaannnnssssllllaaaattttiiiioooonnnnssss The translation table syntax used by Motif is completely specified in the X11R5 Toolkit Intrinsics Documentation. For the complete syntax description, and for general instructions about writing or modifying a translation table, please refer to this document. A brief summary of the translation table format, however, is included below. The syntax is defined as in the binding syntax specification above. Informal descriptions are contained in angle brackets (<>). TranslationTable= [ directive ] { production } directive = ( "#replace" | "#override" | "#augment") "\n" production = lhs ":" rhs "\n" lhs = ( event | keyseq) {"," ( event | keyseq) } keyseq = """ keychar { keychar } """ keychar = ( "^" | "$" | "\\") <ISO Latin 1 character> event = [ modifier_list ] "<" event_type ">" [ count ] {detail} modifier_list = ( ["!"][":"] { modifier } | "None") modifier = [ "~" ] ( "@" <keysym> | <name from table below>) count = "(" <positive integer> [ "+" ] ")" rhs = { action_name "(" [params] ")" } params = string { "," string } The _s_t_r_i_n_g field need not be quoted unless it includes a space or tab character, or any comma, newline, or parenthesis. The entire list of string values making up the _p_a_r_a_m_s field will ba passed to the named action routine. The _d_e_t_a_i_l_s field may be used to specify a keysym that will identify a particular key event. For example, <<<<KKKKeeeeyyyy>>>> is the name of a type of event, but it must be modified by the _d_e_t_a_i_l_s field to name a specific event, such as <<<<KKKKeeeeyyyy>>>>AAAA. MMMMooooddddiiiiffffiiiieeeerrrr NNNNaaaammmmeeeessssThe modifier list, which may be empty, consists of a list of modifier keys that must be pressed with the key sequence. The modifier keys may abbreviated with single letters, as in the following list of the familiar modifiers: s Shift Page 5 (printed 10/24/98) VVVViiiirrrrttttuuuuaaaallllBBBBiiiinnnnddddiiiinnnnggggssss((((lllliiiibbbbrrrraaaarrrryyyy ccccaaaallllUUUUllllNNNN))))IIIIXXXX SSSSyyyysssstttteeeemmmmVVVViiiiVVVVrrrrttttuuuuaaaallllBBBBiiiinnnnddddiiiinnnnggggssss((((lllliiiibbbbrrrraaaarrrryyyy ccccaaaallllllll)))) c or ^ Ctrl (Control) m or $ Meta a Alt Other modifiers are available, such as "Mod5" and "Button2." These have no abbreviation (although the "Button" modifiers may be abbreviated in combination with events, as outlined below). If a modifier list has no entries, and is not "None", it means the position of the modifier keys is irrelevant. If modifiers are listed, the designated keys must be in the specified position, but the unlisted modifier keys are irrelevant. If the list begins with an exclamation point (!), however, the unlisted modifiers may not be asserted. In addition, if a modifier name is preceded by a tilde (~), the corresponding key must _n_o_t be pressed. If a modifier list begins with a colon (:), X tries to use the standard modifiers (Shift and Lock), if present, to map the key event code into a recognized keysym. Event Types These are a few of the recognized event types. Key or KeyDown A keyboard key was pressed. KeyUp A keyboard key was released. BtnDown A mouse button was pressed. BtnUp A mouse button was released. Motion The mouse pointer moved. Enter The pointer entered the widget's window. Leave The pointer left the widget's window. FocusIn The widget has received focus. FocusOut The widget has lost focus. There are some event abbreviations available. For example, <<<<BBBBttttnnnn1111MMMMoooottttiiiioooonnnn>>>> is actually a "Motion" event, modified with the "Button1" modifier (BBBBuuuuttttttttoooonnnn1111<<<<MMMMoooottttiiiioooonnnn>>>>). Similarly, <<<<BBBBttttnnnn3333UUUUpppp>>>>is actually a "BtnUp" event with the "Button3" modifier. These abbreviations are used extensively in the Motif translation tables.
