119 The argument TYPE (default `PRIMARY') says which selection,

120 and DATA specifies the contents. DATA may be any lisp data type
|
|
|
121 that can be converted using the function corresponding to DATA-TYPE
|
|
|
122 in `select-converter-alist'---strings are the usual choice, but
|
|

123 other types may be permissible depending on the DATA-TYPE parameter
|
|
|
124 (if DATA-TYPE is not supplied, the default behavior is window
|
|
|
125 system specific, but strings are always accepted).
|
|
|
126 HOW-TO-ADD may be any of the following:
|
|
|
127
|
|
|
128 'replace-all or nil -- replace all data in the selection.
|
|
|
129 'replace-existing -- replace data for specified DATA-TYPE only.
|

|
130 'append or t -- append data to existing DATA-TYPE data.
|
|
|
131
|
|
|
132 DATA-TYPE is the window-system specific data type identifier

133 (see `register-selection-data-type' for more information).

|
|
442
|
137 between the markers *at whatever time the selection is examined* (note
|
|
|
138 that the window system clipboard does not necessarily duplicate this
|
|
|
139 behavior - it doesn't on mswindows for example).
|
|
428
|
140 Thus, editing done in the buffer after you specify the selection
|
|
|
141 can alter the effective value of the selection.
|
|
|
142
|
|
|
143 The data may also be a vector of valid non-vector selection values.
